▼ The steady increase in volume of goods to be transported over land and water has necessitated the development of efficient and alternative methods of transportation. In current practices considerable amount of transportation delay is caused due to switching between different modes of transportation resulting in economic losses. Another difficulty in the transportation sector arises when handling extremely large objects, such as wind turbines and cargo containers. In order to overcome these difficulties, an alternative method of transportation has been proposed recently. The proposed alternative method consists of the development of a formation control framework using hovercrafts. Formation control is a widely researched topic due its potential benefits in reducing the system cost, structure flexibility and improving the efficiency of the overall system. State-of-the-art methods for formation control are focused towards developing a controller to track a predefined trajectory, and the trajectory generation is an additional problem which is addressed off-line. A path tracking formation control framework is an area which has received less attention in the literature and can have possible improvements. Hence, this thesis work answers the research question of generating a feasible path for a set of initial and final conditions, and tracking the generated path. Model Predictive Controller (MPC) is a promising framework, because of its constraint handling capabilities. Hence, it accounts for the major component of this thesis. A new framework for formation control is proposed which uses spatial-domain parametrization instead of the conventional time-domain parametrization. MPC being a computationally expensive task, the proposed framework reduces the number of decision variables and constraint evaluations which can help to achieve the desired Real Time performance. The specific research question addressed in this thesis work is to develop a path tracking formation control framework while minimising the absolute and relative position error for each vehicle in the formation. A nonlinear dynamic model for the hovercraft is obtained using first principles and its structure is used to design an optimization based controller. An Optimal Control Problem (OCP) is formulated which is solved using direct collocation method. In this method a continuous problem is discretized into a number of collocation points, and the resulting problem is solved using state-of-the-art Nonlinear Program solvers such as, SNOPT and NPSOL. The performance of the proposed framework is illustrated using numerical simulations.

▼ Vehicle control systems have been integral to the performance and stability of a vehicle. In this
thesis, two vehicle control strategies namely, the yaw controller and the yaw-beta controller,
were presented. The control algorithm was based on the model predictive control method. A
simulation environment developed using a two track vehicle model coupled with a tire model
based on the magic tire formula was used to test the controllers in different test scenarios.
These tests were carried out to evaluate the performance of the two controllers with respect to
performance and stability. The results showed small differences between the performance of
the controllers, but enough to indicate the initial assumptions on the behaviour. The yaw-beta
controller was more stable than the yaw controller at the expense of the vehicle performance.
However, the results did not show significant enough differences to determine the magnitude
of any potential gains.

▼ The bottleneck of the maximum road volume in urban areas is the maximum capacity of the traffic flow on the intersection, which is coordinated with Traffic Light Controllers (TLCs). A promising method to decrease the number of stops are Green Light Optimal Speed Advice (GLOSA) systems. These systems will give a speed advice to arriving vehicles based on the schedule of TLCs, which needs to be known and fixed. However, most on-street controllers change their schedule until the last moment to maximize the performance. In this thesis a
predictive controller is developed that is suitable for real-world application based on DIRECTOR; a state-of-the-art
predictive controller. A prediction model is used to predict future arrivals based on available measurements to optimize and fix the schedule in advance. The proposed
controller can enable GLOSA systems to improve performance. Appropriate pre-processing steps are implemented and the optimal input features are selected to improve the performance of a Long Short-Term Memory (LSTM) network to predict future arrivals. All detection data is stationary over time by using the differenced series. The time data is divided into workdays and weekend days to create a binary input and undesirable jumps during midnight are removed. The combination of stop line detectors, queue detectors, arrival detectors and signal states of the controlled and preceding intersections as input maximized the performance. The prediction horizon of the proposed prediction model could be extended. The Normalized Root Mean Square Error (NRMSE) decreased with 17% compared to DIRECTOR. The proposed
controller extends the control horizon and uses multiple prediction models to predict the arrivals for the entire control horizon. The proposed
controller outperforms DIRECTOR with 14 - 38% reduction in terms of vehicle delay and 5 - 32% reduction in terms of numbers of stops based on the scheduling mode. The GLOSA system is an add-on of the
controller and is able to operate without the GLOSA system. The control horizon of the proposed
controller always has a fixed length which is needed to determine the time until green. The implemented GLOSA system will determine the optimal speed based on the time until green and the expected delay due to the surrounding vehicles. The proposed
controller is a cloud controlled application. Therefore, it is possible to adjust the setup (i.e. scheduling modes) during the day. Enabling GLOSA all day except during rush hours will lead to 3 - 4% reduction in terms of vehicle delay and 29 - 32% reduction in terms of numbers of stops based on the scheduling mode. This setup of the proposed
controller is also competitive with the hand-crafted non-
predictive on-street
controller. Compared with this
controller, the proposed
controller will reduce the number of stops with 26% at the cost of 16% increase in vehicle delay. The proposed
controller is designed conform the safety standards used on-street. Permission is received from the provincial government to do on-street pilots with the…

▼ Model Predictive Control (MPC) has shown promising results in the control of urban traffic networks, but has one major drawback. The, often nonlinear, optimization that has to be performed at every control time step is computationally too complex to use MPC controllers for real-time implementations (i.e. when the online optimization is performed within the control time interval of the controlled system). This thesis proposes a parametrized MPC control approach to lower the computational complexity of the MPC controllers and to strive for real-time implementability. In parametrized MPC, the original decision variables (i.e. the inputs of the system) become a function of a parametrized control law and the parameters of this control law become the new decision variables of the optimization problem. The goal is to lower the computational complexity by reducing the number of decision variables with limited performance decrease. In this thesis, three parametrized control laws are proposed that can be used in the parametrized MPC approach for urban traffic networks. These three control laws are constructed based on the prediction model of the (parametrized) MPC controller, on ART-UTC, an existing control method, and by using supervised learning. The system performance and computational complexity of the different parametrized MPC controllers are compared to that of a conventional MPC controller by performing an extensive simulation-based case study in which different optimization algorithms, emissions, and parameter update time steps are considered. The simulation results show that the control law based on the prediction model results in a parametrized MPC controller which is real-time implementable, uses 2 parameters that are constant over the control horizon per intersection, and has a system performance decrease of less than 3%.

▼ In an automotive diesel airpath application, the controller is required to track reference values of intake manifold (boost) pressure and exhaust gas recirculation (EGR) rate. EGR rate is the ratio of the EGR outflow rate to the combined EGR and compressor outflow rates. The reference values for these output variables are determined by a high level controller based on the current engine operating condition characterised by an engine rotational speed and a fuelling rate. Perfect tracking of these references in a drive cycle ensures optimal driver demand responsiveness, fuel efficiency, and satisfaction of legislated emission limits. However, diesel engine airpath control is challenging owing to its nonlinear multivariable nature.
Conventional approaches use look-up tables and proportional-integral-differential (PID) loops ignoring the cross-sensitivities that can affect the controller performance. Furthermore, these approaches do not guarantee satisfaction of operating and reliability constraints on manifold pressures and physical limitations of the actuators. On the other hand, the constraint handling ability of model predictive control (MPC) makes it an ideal choice of control architecture for constrained multi-input multi-output systems, such as diesel engines. However, efficient calibration of typical implementations of MPC is hindered by the high number of tuning parameters and their non-intuitive correlation with the output response. Additionally, modelling errors might lead to constraint violation and loss of recursive feasibility.
This thesis proposes a robust switched linear time invariant (LTI) MPC architecture for diesel airpath that utilises multiple local controllers that require low calibration effort. In order to reduce the number of effective tuning parameters to aid rapid calibration, first, structural modifications are introduced to the traditional MPC formulation by constraining the outputs within exponentially decaying envelopes and an appropriate cost function parameterisation. Subsequently, a methodology based on sequential convex program (SCP) is proposed to estimate maximal disturbance set that can be handled by each local controller under limited control authority arising due to input saturations typically observed in diesel engine operation. Constraint tightening approach is used to provide robust feasibility guarantees in the face of uncertainties originating from the maximal disturbance set and due to controller switching. In addition, a procedure is proposed for identifying the switched controllers requiring further tuning using feedback from performance over drive cycles. The developed switched LTI-MPC architecture is implemented on rapid prototyping hardware and experimentally demonstrated on a diesel engine test rig. The calibration efficacy of the controller architecture is demonstrated at a steady state condition for fuelling steps and over drive cycles. Furthermore, the control system is shown to track output references while maintaining all input and state constraints in…

▼ This research deals with the modeling and control of a
plasticating twin screw extruder (TSE) that will be used to obtain
consistent product quality. The TSE is a widely used process
technology for compounding raw polymers. Compounding creates a
polymer with improved properties that satisfy the demand of modern
plastic applications. Modeling and control of a TSE is challenging
because of its high nonlinearity, inherent time delay, and multiple
interactive dynamic behavior. A complete methodology is proposed in
this thesis to design an advanced control scheme for a TSE. This
methodology was used to develop a model predictive control scheme
for a laboratory scale plasticating TSE and to implement the
control scheme in real-time. The TSE has a processing length of 925
mm and a length to screw diameter ratio (L/D) of 37. High density
polyethylenes with different melt indices were used as processing
materials. Manipulated variables and disturbance variables were
selected based on knowledge of the process. Controlled variables
were selected using a selection method that includes a steady state
correlation between process output variables and product quality
variables, and dynamic considerations. Two process output
variables, melt temperature (Tm) at the die and melt pressure (Pm)
at the die, were selected as controlled variables. A new modeling
approach was proposed to develop grey box models based on
excitation in the extruder screw speed (N), one of the manipulated
variables. The extruder was excited using a predesigned random
binary sequence (RBS) type excitation in N and nonlinear models
relating Tm and Pm to N were developed using this approach. System
identification techniques were used to obtain model parameters. The
obtained models have an autoregressive moving average with
exogenous (ARMAX) input structure and the models explain the
physics of the extrusion process successfully. The TSE was also
excited using a predesigned RBS in the feed rate (F) as a
manipulated variable. Models relating Tm and Pm to F were developed
using a classical system identification technique; both models have
ARMAX structures. The model between Pm and F was found to give
excellent prediction for data obtained from a stair type
excitation, indicating that the obtained models provide a good
representation of the dynamics of the twin screw extruder. Analysis
of the TSE open loop process indicated two manipulated variables, N
and F, and two controlled variables, Tm and Pm. Thus, a model
predictive controller (MPC) was designed using the developed models
for this 2X2 system and implemented in real-time. The performance
of the MPC was studied by checking its set-point tracking ability.
The robustness of the MPC was also examined by imposing external
disturbances. Finally, a multimodel operating regime was used to
model Tm and N. The operating regime was divided based on the screw
speed, N. Local models were developed using system identification
techniques. The global model was developed by combining local
models using fuzzy logic methodology.…

▼ This thesis presents the development of self adaptive flight controller for an unmanned helicopter system under hovering manoeuvre. The neural network (NN) based model predictive control (MPC) approach is utilised in this work. We use this controller due to its ability to handle system constraints and the time varying nature of the helicopter dynamics. The non-linear NN based MPC controller is known to produce slow solution convergence due to high computation demand in the optimisation process. To solve this problem, the automatic flight controller system is designed using the NN based approximate predictive control (NNAPC) approach that relies on extraction of linear models from the non-linear NN model at each time step. The sequence of control input is generated using the prediction from the linearised model and the optimisation routine of MPC subject to the imposed hard constraints. In this project, the optimisation of the MPC objective criterion is implemented using simple and fast computation of the Hildreth's Quadratic Programming (QP) procedure.
The system identification of the helicopter dynamics is typically performed using the time regression network (NNARX) with the input variables. Their time lags are fed into a static feed-forward network such as the multi-layered perceptron (MLP) network. NN based modelling that uses the NNARX structure to represent a dynamical system usually requires a priori knowledge about the model order of the system. Low model order assumption generally leads to deterioration of model prediction accuracy. Furthermore, massive amount of weights in the standard NNARX model can result in an increased NN training time and limit the application of the NNARX model in a real-time application. In this thesis, three types of NN architectures are considered to represent the time regression network: the multi-layered perceptron (MLP), the hybrid multi-layered perceptron (HMLP) and the modified Elman network. The latter two architectures are introduced to improve the training time and the convergence rate of the NN model. The model structures for the proposed architecture are selected using the proposed Lipschitz coefficient and k-cross validation methods to determine the best network configuration that guarantees good generalisation performance for model prediction.
Most NN based modelling techniques attempt to model the time varying dynamics of a helicopter system using the off-line modelling approach which are incapable of representing the entire operating points of the flight envelope very well. Past research works attempt to update the NN model during flight using the mini-batch Levenberg-Marquardt (LM) training. However, due to the limited processing power available in the real-time processor, such approaches can only be employed to relatively small networks and they are limited to model uncoupled helicopter dynamics. In order to accommodate the time-varying properties of helicopter dynamics which change frequently during flight, a recursive Gauss-Newton (rGN) algorithm is…

▼ In this thesis, a cognitive neural predictive controller system has been designed to guide a nonholonomic wheeled mobile robot during continuous and non-continuous trajectory tracking and to navigate through static obstacles with collision-free and minimum tracking error. The structure of the controller consists of two layers; the first layer is a neural network system that controls the mobile robot actuators in order to track a desired path. The second layer of the controller is cognitive layer that collects information from the environment and plans the optimal path. In addition to this, it detects if there is any obstacle in the path so it can be avoided by re-planning the trajectory using particle swarm optimisation (PSO) technique. Two neural networks models are used: the first model is modified Elman recurrent neural network model that describes the kinematic and dynamic model of the mobile robot and it is trained off-line and on-line stages to guarantee that the outputs of the model will accurately represent the actual outputs of the mobile robot system. The trained neural model acts as the position and orientation identifier. The second model is feedforward multi-layer perceptron neural network that describes a feedforward neural controller and it is trained off-line and its weights are adapted on-line to find the reference torques, which controls the steady-state outputs of the mobile robot system. The feedback neural controller is based on the posture neural identifier and quadratic performance index predictive optimisation algorithm for N step-ahead prediction in order to find the optimal torque action in the transient to stabilise the tracking error of the mobile robot system when the trajectory of the robot is drifted from the desired path during transient state. Three controller methodologies were developed: the first is the feedback neural controller; the second is the nonlinear PID neural feedback controller and the third is nonlinear inverse dynamic neural feedback controller, based on the back-stepping method and Lyapunov criterion. The main advantages of the presented approaches are to plan an optimal path for itself avoiding obstructions by using intelligent (PSO) technique as well as the analytically derived control law, which has significantly high computational accuracy with predictive optimisation technique to obtain the optimal torques control action and lead to minimum tracking error of the mobile robot for different types of trajectories. The proposed control algorithm has been applied to monitor a nonholonomic wheeled mobile robot, has demonstrated the capability of tracking different trajectories with continuous gradients (lemniscates and circular) or non-continuous gradients (square) with bounded external disturbances and static obstacles. Simulations results and experimental work showed the effectiveness of the proposed cognitive neural predictive control algorithm; this is demonstrated by the minimised tracking error to less than (1 cm) and obtained smoothness of the torque control…

▼ In the 21st century, because of the exhausting of oil, coal and other non-renewable energy, human beings enter a period of large-scale exploitation and utilization of renewable energy. Renewable energy generation become an important way for new energy utilization, however, as more and more distributed generation connect to power distribution network, the traditional distribution network structure will be changed. A large number of distributed generation applications of modern power electronic technology, have also produced a lot of harmonics to impact the power quality. It will threaten the safe operation of the distribution network and obstruct the utilization of renewable energy. The concept of microgrid provides a new thinking for the application of renewable energy. Microgrid can make full use of the characteristics of the renewable energy and it is the key of the future resources and environment for human beings. We can predict that, microgrid construction will be rapidly developed in 21st century, based on the utilization of renewable energy.
In order to coordinate the contradiction between power grid and distributed generation, the concept of microgrid arises at the historic moment. Microgrid has two operation modes: islanded mode and grid-connected mode. By theoretically analyzing, simulation model construction and result analyzing, the microgrid coordinated control strategies will be studied in this paper.
Firstly, this paper starts from the microgrid operation control mode, respectively establishing the traditional control strategy of simulation for the isolated and connected microgrid. The isolated grid control strategies is V/f control strategy based on droop characteristic and the connected grid control strategies is P/Q control strategy.
Second, the model
predictive control is introduced in chapter three including its principle and application. In the case study, the traditional PI
controller is compared with model
predictive control
controller in single distributed generation system to introduce advantages of model
predictive control method.
Last, the model of microgrid with multiple distributed generations is built in MATLAB/Simulink. There are three cases in this model: working model switches between grid-connected and islanded mode; increase and decrease load in islanded mode; disconnect one PV system at certain time in islanded mode. By analyzing results of three cases, the MPC
controller can achieve desirable efficiency of power control. Meanwhile, the voltage and frequency are working in the required range of the system. That proves the effectiveness of MPC
controller.

▼ This thesis presents the development of self adaptive flight controller for an unmanned helicopter system under hovering manoeuvre. The neural network (NN) based model predictive control (MPC) approach is utilised in this work. We use this controller due to its ability to handle system constraints and the time varying nature of the helicopter dynamics. The non-linear NN based MPC controller is known to produce slow solution convergence due to high computation demand in the optimisation process. To solve this problem, the automatic flight controller system is designed using the NN based approximate predictive control (NNAPC) approach that relies on extraction of linear models from the non-linear NN model at each time step. The sequence of control input is generated using the prediction from the linearised model and the optimisation routine of MPC subject to the imposed hard constraints. In this project, the optimisation of the MPC objective criterion is implemented using simple and fast computation of the Hildreth's Quadratic Programming (QP) procedure.
The system identification of the helicopter dynamics is typically performed using the time regression network (NNARX) with the input variables. Their time lags are fed into a static feed-forward network such as the multi-layered perceptron (MLP) network. NN based modelling that uses the NNARX structure to represent a dynamical system usually requires a priori knowledge about the model order of the system. Low model order assumption generally leads to deterioration of model prediction accuracy. Furthermore, massive amount of weights in the standard NNARX model can result in an increased NN training time and limit the application of the NNARX model in a real-time application. In this thesis, three types of NN architectures are considered to represent the time regression network: the multi-layered perceptron (MLP), the hybrid multi-layered perceptron (HMLP) and the modified Elman network. The latter two architectures are introduced to improve the training time and the convergence rate of the NN model. The model structures for the proposed architecture are selected using the proposed Lipschitz coefficient and k-cross validation methods to determine the best network configuration that guarantees good generalisation performance for model prediction.
Most NN based modelling techniques attempt to model the time varying dynamics of a helicopter system using the off-line modelling approach which are incapable of representing the entire operating points of the flight envelope very well. Past research works attempt to update the NN model during flight using the mini-batch Levenberg-Marquardt (LM) training. However, due to the limited processing power available in the real-time processor, such approaches can only be employed to relatively small networks and they are limited to model uncoupled helicopter dynamics. In order to accommodate the time-varying properties of helicopter dynamics which change frequently during flight, a recursive Gauss-Newton (rGN) algorithm is…

▼ For the last two decades, with the fast development of electronics, cheap and lightweight flight controllers, accelerometers, global positioning system and cameras have become readily available, which lead to a rapid growth of small commercial multi-rotor Unmanned Aerial Vehicles (UAV). The multi-rotor unmanned aerial vehicles are unstable systems due to their physical structures and feedback control systems underpin their operations and are paramount in the design and implementation of unmanned aerial vehicles. This thesis is dedicated to the topics of quadrotor controller design, automatic tuning and performance evaluation of their feedback control systems. Six key contributions are made in this research: (1) critical evaluation of conventional model-based quadrotor UAV controller design; (2) novel quadrotor PID control automatic tuning process with potential wide applications; (3) quadrotor control system performance assessment method via step response identification; (4) design and performance assessment of cascade and centralized quadrotor control using Model Predictive Control (MPC); (5) design and simulation of Quadrotor Discrete-Time One-step-ahead Predictive Control (DOPC) design; (6) design and implementation of two quadrotor UAV test rigs for validations of the proposed control strategies. In this thesis, a critical review of the conventional conventional modelbased quadrotor flight controller design is firstly conducted. Numerical simulations and experimental tests show the simplified integrator model and the neglected dynamics, which are commonly used in the conventional quadrotor controller design, can dramatically affect the closed-loop responses of the systems. The problems existed in the conventional modelbased PID controller design serve the motivation to develop the PID autotuner. The key idea behind the proposed auto-tuner is to fit the dominant dynamics of a physical plant into a simplified integrator plus delay model, which is then used to design the PID controller. The auto-tuner ensures a sound closed-loop control performance, without endangering the unmanned aerial vehicles and providing engineers and practitioners with reliable controller parameters. Another important issue for future quadrotor applications is how to reliably assess its closed-loop control performance and identify potential faults before flight. To address this problem, a novel approach to assess the closed-loop control performance of a quadrotor UAV is proposed in this thesis, which gives an intuitive way to more precisely evaluate the designed controllers and to obtain better controller tuning parameters. The auto-tuner and the proposed performance assessment scheme are evaluated on the self-made test rigs with final validations on flight tests. This thesis also covers the topic of quadrotor linear and nonlinear predictive control. For linear MPC, both centralized MPC and cascade MPC control architectures are designed for the quadrotor position controls. From the comparison, the advantages of cascade MPC over centralized…

▼ O escopo desta dissertação é o desenvolvimento de um método para detectar os modelos da matriz dinâmica que estejam degradando o desempenho de controladores preditivos baseados em modelos. O método proposto se baseia na análise de correlação cruzada entre o erro nominal do controlador em malha fechada e a uma estimativa da contribuição de cada canal para o cálculo da saÃda, filtrada pela função de sensibilidade do controlador. Esse método pode ser empregado na auditoria de controladores com variáveis controladas em setpoints e/ou com variáveis que operem entre faixas, como é usual de se encontrar na indústria. Esta dissertação apresenta os resultados da aplicação bem sucedida do método no sistema de quatro tanques (JOHANSSON, 2000), para o qual três cenários foram avaliados. No primeiro cenário, o método localizou corretamente discrepâncias de ganho e de dinâmica de modelos de um controlador preditivo baseado em modelos (Model-based Predictive Controller, ou controlador MPC). No segundo, o método foi utilizado para avaliar a influência de uma variável externa para melhorar o desempenho de um controlador afetado por distúrbios não medidos. No terceiro cenário, o método localizou canais com modelos nulos que deveriam ser incluÃdos na matriz de controle de um controlador MPC de estrutura descentralizada. Os resultados deste estudo de caso foram comparados com aqueles obtidos pelo método proposto por BADWE, GUDI e PATWARDHAN (2009), constatando-se que o método proposto é mais robusto que o método usado na comparação, não demandando ajustes de parâmetros por parte do usuário para fornecer bons resultados. A dissertação inclui também um estudo de caso da aplicação industrial do método na auditoria de desempenho de um controlador preditivo linear de estrutura descentralizada, com doze variáveis controladas, oito manipuladas e quatro distúrbios não medidos, aplicado a um sistema de fracionamento de propeno e propano em uma indústria petroquÃmica. A auditoria permitiu reduzir o escopo de revisão do controlador a dezenove canais da matriz, sendo que quatorze destes correspondiam a canais com modelos nulos que deveriam ser incluÃdos na matriz. A eficácia do método foi comprovada repetindo-se a avaliação da qualidade de modelo para todas as variáveis controladas.
The scope of this dissertation is the development of a method to detect the models of the dynamic matrix that are affecting the performance of model-based predictive controllers. The proposed method is based on the cross correlation analysis between the nominal controller error and an estimate of the contribution of each channel to the controller output, filtered by the controller nominal sensitivity function. The method can be used in the performance assessment of controllers employing variables controlled at the setpoint and/or those controlled within ranges. This dissertation presents the results of the successful application of the method to the quadruple-tank process (JOHANSSON, 2000), for which three scenarios were evaluated. In the first scenario, the method…

▼ This thesis considers the problem of control of nonlinear systems subject to limited availability
of measurements and uncertainty in model parameters. To address this problem, first a
linear offset free MPC is designed. Subsequently, a Lyapunov-based offset free MPC design
is presented to handle structured uncertainty subject to constant disturbances. The controller's ability to handle unstructured uncertainty and measurement noise is demonstrated through simulation examples. Next, the problem of handling lack of state measurements as well as uncertainty is considered. To achieve simultaneous state and disturbance parameter estimation, a Lyapunov-based model predictive controller (MPC) is integrated with a moving horizon based mechanism, to achieve (where possible) offset elimination in the unmeasured states as well. A chemical reaction process example is presented to illustrate the key points. Finally its efficacy is demonstrated through a polymerization process example.

Automatic Parking and Path Following Control for a Heavy-Duty Vehicle.

▼ The interest in autonomous vehicles has never been higher and there are several components that need to function for a vehicle to be fully autonomous; one of which is the ability to perform a parking at the end of a mission. The objective of this thesis work is to develop and implement an automatic parking system (APS) for a heavy-duty vehicle (HDV). A delimitation in this thesis work is that the parking lot has a known structure and the HDV is a truck without any trailer and access to more computational power and sensors than today's commercial trucks. An automatic system for searching the parking lot has been developed which updates an occupancy grid map (OGM) based on measurements from GPS and LIDAR sensors mounted on the truck. Based on the OGM and the known structure of the parking lot, the state of the parking spots is determined and a path can be computed between the current and desired position. Based on a kinematic model of the HDV, a gain-scheduled linear quadratic (LQ) controller with feedforward action is developed. The controller's objective is to stabilize the lateral error dynamics of the system around a precomputed path. The LQ controller explicitly takes into account that there exist an input delay in the system. Due to minor complications with the precomputed path the LQ controller causes the steering wheel turn too rapidly which makes the backup driver nervous. To limit these rapid changes of the steering wheel a controller based on model predictive control (MPC) is developed with the goal of making the steering wheel behave more human-like. A constraint for maximum allowed changes of the controller output is added to the MPC formulation as well as physical restrictions and the resulting MPC controller is smoother and more human-like, but due to computational limitations the controller turns out less effective than desired. Development and testing of the two controllers are evaluated in three different environments of varying complexity; the simplest simulation environment contains a basic vehicle model and serves as a proof of concept environment, the second simulation environment uses a more realistic vehicle model and finally the controllers are evaluated on a full-scale HDV. Finally, system tests of the APS are performed and the HDV successfully parks with the LQ controller as well as the MPC controller. The concept of a self-parking HDV has been demonstrated even though more tuning and development needs to be done before the proposed APS can be used in a commercial HDV.

▼ A retroalimentação de controladores preditivos que utilizam modelos em espaço de estado pode ser realizada de duas formas: (a) correção por bias, em que as saÃdas preditas são corrigidas adicionando-se um valor proporcional a discrepância encontrada entre o valor medido atual e sua respectiva predição e por (b) retroalimentação dos estados, onde se determinam as condições iniciais através da estimação dos estados, e a partir de uma melhor condição inicial se realizam as predições futuras usadas no cálculo das ações de controle. Nesta dissertação estas duas abordagens são comparadas utilizando a Planta Laboratorial de Seis Tanques Esféricos. As técnicas de Filtro de Kalman Estendido (EKF) e Filtro de Kalman Estendido com Restrições (CEKF) foram empregadas para estimar os estados não medidos. Inicialmente foram feitos testes off-line destes algoritmos de estimação. Para estes testes são utilizados uma série de dados da planta laboratorial do estudo de caso, na qual são estudadas as influências de diversos fatores de ajuste que determinam a qualidade final de estimação. Estes ajustes serviram de base para a aplicação destes algoritmos em tempo real, quando então, estimadores de estados estão associados ao sistema de controle do processo baseado em um algoritmo de controle preditivo. Após se ter certificado a qualidade das estimações de estado, partiu-se para sua utilização como uma alternativa de retroalimentação de controladores preditivos. Estes resultados foram comparados com os obtidos através da correção simples por bias. Os resultados experimentais apontam para uma marginal piora devido à retroalimentação por estimadores de estados frente à correção por bias, pelo menos para o caso do controlador preditivo linear utilizado na comparação. Entretanto, espera-se que resultados melhores sejam obtidos no caso de modelos preditivos não-lineares, uma vez que nestes casos o modelo é bem mais sensÃvel à qualidade da condição inicial.
The feedback of controllers that use predictive models in state space can be accomplished in two ways: (a) bias correction, where the predicted outputs are corrected by adding a value proportional to the discrepancy found between the current measurement and its respective prediction; and by (b) state feedback, which establishes the initial conditions through the states estimation, and from a better initial condition are carried out the future predictions used in the calculation of control. In this thesis these two approaches are compared using a Laboratorial Plant of Six Spherical Tanks. The techniques of Extended Kalman Filter (EKF) and Constraint Extended Kalman Filter (CEKF) were used to estimate the unmeasured states. Initially, tests were carried out off-line for theses estimation algorithms. For such testing are used a dataset of the plant in case study, in which are studied the influences of several adjustment factors that they determine the final quality of estimation. These adjustments were used of base for the application of these algorithms in real time, when then state…

▼ O escopo desta dissertação é o desenvolvimento de uma metodologia para identificar os modelos de canais da matriz dinâmica que estejam degradando o desempenho de controladores preditivos, ou MPC (Model Predictive Control), baseado nas técnicas de auditoria e diagnóstico deste tipo de controlador propostas por BOTELHO et al. (2015) e BOTELHO; TRIERWEILER; FARENZENA (2016) e CLARO (2016). A metodologia desenvolvida contempla dois métodos distintos. O primeiro, chamado método direto compensado, tem como base o método direto de identificação em malha fechada (LJUNG, 1987)e compensa cada saÃda medida do processo de modo a se reter apenas a contribuição do canal que se deseja identificar. O segundo, chamado método do erro nominal, utiliza a definição de saÃda nominal do processo, proposta por BOTELHO et al. (2015), como métrica para se quantificar o quão próximo o modelo está do comportamento da planta através da minimização do erro nominal. Os métodos foram aplicados ao sistema de quatro tanques cilÃndricos (JOHANSSON, 2000) para dois cenários distintos, sendo o primeiro um sistema 2x2 em fase não mÃnima contendo um MPC trabalhando com setpoint e o segundo um sistema 4x4 em fase mÃnima com o MPC atuando por faixas. Para o sistema 2x2, se avaliou a influência da localização do canal discrepante (dentro ou fora da diagonal principal da matriz dinâmica de transferência) na eficácia dos métodos. Para o sistema 4x4, o estudo foi voltado para a eficácia dos métodos frentes a controladores que atuam dentro de limites para as variáveis. Os modelos identificados foram comparados pela capacidade de identificar um modelo que capturasse o zero de transmissão da planta e o RGA dinâmico, par ao sistema 2x2, e pelas respostas degrau e diagrama de Bode para o sistema 4x4. O método direto compensado resultou em baixo erro relativo no valor do zero para a discrepância na diagonal principal da matriz dinâmica e alto valor quando a discrepância se encontrava fora da diagonal principal. O método do erro nominal, por sua vez, foi capaz de identificar um modelo cujo zero de transmissão possuÃa baixo erro relativo frente ao zero da planta em ambos os cenários. No cenário do controlador atuando por faixas, os métodos propostos obtiveram melhores estimativas dos modelos quando comparados com o método concorrente, uma vez que apresentou alto percentual de aderência das saÃdas simuladas com as saÃdas medidas. Em todos os cenários estudados, o método do erro nominal se mostrou capaz de identificar um modelo mais robusto, pois este apresentou RGA dinâmico compatÃvel com a planta em todo o range de frequências analisado.

▼ Avec le développement récent de régulateurs innovants pour le bâtiment, il devient nécessaire de mettre au point une méthode de test qui soit à la fois rapide, reproductible et réaliste. La méthode développée dans cette thèse permet d'obtenir des performances annuelles de régulateurs de pompes à chaleurs (PAC) géothermiques en seulement quelques jours de test. Basé sur une technique d'émulation déjà utilisée pour des tests de PAC géothermiques et de systèmes solaires combinés, le test permet d'incorporer le régulateur et la PAC réels dans un environnement de simulation calibré par des mesures in-situ. Chaque jour de test correspond à un jour type de chaque mois. Le développement de la méthode consiste à déterminer la séquence de jours types optimale permettant une bonne estimation des performances. La méthode est ensuite testée expérimentalement sur le banc semi-virtuel pour comparer un régulateur prédictif à un régulateur conventionnel sur une saison de chauffage. Pour les besoins de la méthode, un régulateur prédictif de PAC géothermiques est développé. Ce régulateur utilise des réseaux de neurones pour la prévision des données météo et de la température ambiante. Un nouveau module pour la prévision des températures dans le plancher chauffant et les sondes géothermiques est proposé. Le régulateur prédictif est testé par simulation sur une saison de chauffage pour différents climats et types de maisons individuelles. En fonction de la référence, les économies d'énergie réalisées varient entre 6% et 15%.
With the recent development of innovative controllers for the building, there is a need to develop a testing method that is fast, reproducible and realistic. The method developed in this study aims to estimate the annual performance of ground source heat pump (GSHP) controllers in only a few days of test. Based on emulation techniques already used for GSHP and solar combined systems, the test immerses the controller and a real GSHP in a simulated environement that is calibrated with in-situ data. Each day of test represents a typical day of the month. The development of the method consists in determining the optimal typical days that ensure an accurate estimation of annual performance. The method is then experimentally tested on the semi-virtual test bench for the comparison of a predictive controller and a conventionnal controller over an entire heating season.To develop the method, a predictive controller for GSHP is elaborated. The controller is based on artificial neural networks used for the prediction of weather data and indoor temperature. A new module for the prediction of floor heating and boreholes fluid temperatures is also proposed. The predictive controller is tested by simulation over a heating season for various climates and types of single family house. According to the reference case, the energy savings vary between 6% and 15%.

▼ The topic of study within includes the development and application of nonlinear control technologies on sampled systems. Discrete control structures are introduced that expand on existing differential geometric and predictive control methods. The differential geometric techniques are described from the error trajectory context, which are typically only derived for continuous application. The discrete error trajectory controllers introduced have one of two configurations. The first configuration requires satisfaction of the error trajectory objective at the next sampling interval through prediction of system behaviour over the controller sampling interval. This objective found limited success and it is observed that satisfaction of the error trajectory objective at discrete intervals does not generally result in the intended response. The second configuration minimizes the integrated distance from the error manifold defined by the error trajectory objective over the entire controller sampling interval. It is observed that this integrated error trajectory controller best emulates the intent of the continuous controller in the discrete domain. Techniques borrowed from predictive control are incorporated into the integrated error trajectory controller such as input move suppression and constraints to produce an optimal error trajectory controller, further improving performance. The predictive control method introduced utilizes a transformation of the input space. The differentiating property of input transformation predictive control (ITPC) from other methods is the prediction technique that is capable of estimating the future behaviour of nonlinear systems through elementary matrix operations similar to the dynamic matrix control (DMC) prediction technique. This is achieved by separation of the steady state and dynamic system properties and the introduction of an intermediate state prediction layer. This allows for the nonlinear prediction of system behaviour without the need to numerically integrate the system model. Two example systems are used to demonstrate application of the discrete error trajectory and ITPC on nonlinear controllers. Performance for these control structures is compared to technologies accepted within the control community for a broad range for characteristics including, computation efficiency, design effort and other nonlinear performance criteria, with favourable results.

▼ The cyber-physical system is the keyword of the fourth industrial revolution. The internet changed the way that humans interact with each other, and cyber-physical systems will change the way that we interact with the physical world around us. There are five levels for designing cyber-physical systems, the most important level among these five levels in which the physical world gets connected to the cyber world is the cyber level in which a cyber model of the system is built, following levels and any further decision will heavily depend on the cyber model that is derived in this level. In this project, the network of wireless control cars will be used as a simulation of Wireless Networked Control system for testing and implementation of the cyber-physical algorithms, this network of cars is composed of three parts: cars, controllers and communication link. The cyber model of the cars will be derived in the first part and will be validated through simulation. In the second part, three controllers will be designed for the cyber model and physical model, these controllers are: the controller for closed-loop control of one car, controller for distance and speed control of two cars and controller for distance and speed control of platoon of cars, all of these controllers will be designed according to PID, Linear Quadraticand Model Predictive Control. Finally, the communication link between the cyber controller and physical device will be implemented and a cyber controller will be used for controlling the physical system.

▼ Government regulations and growing concerns regarding global warming has
lead to an increasing number of passenger vehicles on the roads today that are not
powered by the conventional internal combustion (IC) engine. Automotive manufacturers
have introduced electric powertrains over the last 10 years which have
introduced new challenges regarding powering accessory loads historically reliant on
the mechanical energy of the IC engine. High density batteries are used to store
the electrical energy required by an electric powertrain and due to their relatively
narrow acceptable temperature range, require liquid cooling. The cooling system in
place currently utilizes the A/C compressor for cooling and a separate electric element
for heating which is energy expensive when the source of energy is electricity.
The proposed solution is a thermoelectric heat pump for both heating and cooling.
A model
predictive controller (MPC) is designed, implemented and tested to
optimize the operation of the thermoelectric heat pump. The model
predictive
controller is chosen due to its ability to accept multiple constrained inputs and
outputs as well as optimize the system according to a cost function which may
consist of any parameters the designer chooses. The system is highly non-linear and
complex therefore both physical modelling and system identi cation were used to
derive an accurate model of the system. A steepest descent algorithm was used for
optimization of the cost function.
The
controller was tested in a test bench environment. The results show the
thermoelectric heat pump does hold the battery at the speci ed set point however
more optimization was expected from the
controller. The
controller fell short of
expectation due to operational restriction enforced during design meant to simplify
the problem. The MPC
controller is capable of much better performance through
adding more detail to the model, an improved optimization algorithm and allowing
more flexibility in set point selection.

▼ A novel model-based and
predictive energy supervisory
controller for hybrid electric vehicles (HEVs) is presented. Its objective is to minimize the fuel consumption (FC) of HEVs using the information on the current state of charge (SoC) of the battery, data available from a standard on-board navigation system and real-time traffic data from an on board computer driver assistance systems. This objective is achieved using a
predictive reference signal generator (pRSG) in combination with a non-
predictive reference tracking
controller for the battery SoC. The pRSG computes the desired battery SoC trajectory as a function of vehicle position such that the recuperated energy is maximized despite the constraints on the battery SoC. Simulation results of the proposed
predictive strategy in hilly driving profiles are compared with non-
predictive strategies to show improvements in fuel economy. A parallel HEV is analyzed. However, the proposed method is independent of the powertrain topology. Therefore, the method is applicable to all types of HEVs.

▼ Driver errors are a critical factor of the majority of car crashes. Autonomous vehicles take drivers and driver errors out of the equation, so they are being developed to reduce car crashes. However, in some situations, a crash is unavoidable even for an autonomous vehicle. An autonomous vehicle is expected to behave properly in such a situation. Crashing into different obstacles have different costs based on the injury or damage the crash might cause. In an imminent crash situation, an autonomous vehicle is expected to consider these costs and plan a trajectory that avoids the obstacles with the highest priorities.
In this thesis, a motion planning Model Predictive Controller (MPC) has been developed that plans the vehicle’s trajectories based on the obstacle’s priorities. Motion planning MPCs usually use potential fields or obstacle constraints for obstacle avoidance. However, they treat all the obstacles in the same way. Two methods have been developed in this thesis to prioritize obstacles in motion planning. The first method prioritizes obstacles based on their avoidance necessities. It categorizes obstacles as crossable and non-crossable, and assigns a potential function to each category corresponding to its avoidance necessity. The second method prioritizes obstacles based on their corresponding crash costs. It applies lexicographic optimization on the MPC to prioritize the non-crossable obstacles according to their crash costs by prioritizing their corresponding constraints.
A motion planning MPC problem is generally a nonlinear MPC problem. It is usually approximated by a quadratic MPC problem to become implementable in real time. In this thesis, a quadratic motion planning MPC has been developed. This MPC has a linear vehicle model and linear vehicle and obstacle constraints. The linear vehicle model along with the linear vehicle constraints should be able to model the nonlinear vehicle behavior. A linear bicycle model has been utilized, and linear tire constraints have been developed such that they can model the nonlinear vehicle behavior at the tire force limits. Moreover, a linear obstacle constraint set misses some of the feasible trajectories in the process of convexifying the obstacle-free area. An iterative obstacle avoidance method has been developed in this thesis to reduce the number of feasible trajectories missed due to the convexification.
The performance of the developed motion planning MPC has been evaluated in a computer simulation with a high fidelity vehicle model. The MPC has been simulated for test scenarios to evaluate its performance in autonomous driving and prioritizing obstacles. The capabilities of the developed tire constraints and the iterative obstacle avoidance method have also been observed. The motion planning MPC has also been implemented on an autonomous test vehicle platform to show that it is implementable in real time and to validate the simulation results.

▼ Neste trabalho foi construido um sistema de hardware e software acoplado em uma incubadora comercial transformando-a em uma plataforma de estudo sobre o processo de umidade e temperatura caracteristico deste sistema. Atraves do software em um computador e possivel fazer medicoes das variaveis controladas e modificar os valores das variÃveis manipuladas, neste caso, o resistor de aquecimento do ar, no sistema de temperatura, e o resistor de aquecimento da agua no sistema de umidade. Foram identificados modelos do processo e um controlador preditivo do tipo GPC foi projetado para atender os criterios definidos na norma NBR IEC 60601-2/19. Para verificar o cumprimento destes critÃrios pelo controlador foi construido um sistema de hardware e software para realizar alguns dos ensaios previstos pela norma, criando um sistema de avaliacao de desempenho
do comportamento das grandezas de temperatura e umidade relativa do ar no interior de incubadoras neonatais conforme a norma. O desempenho do controlador projetado foi
comparado com o controlador pre existente da incubadora comercial. Foi verificado que o controlador projetado conseguiu atender os critÃrios da norma com sobre-sinal e erro de regime menores que os obtidos pelo controlador ja pre-existente na incubadora comercial.
In this work was built a system of hardware and software engaged in a commercial incubator turning it into a platform to study the process of humidity and temperature characteristic of this system. Using the software on a computer can make measurements of controlled variables and modify the values of the manipulated variables, in this case
the resistor heating the air in the temperatureâs system and the heating resistor of the water in the humidityâs system. Process models were identified and a predictive controller
type GPC is designed to meet the criteria defined in the standard NBR IEC 60601-2/19.
To verify compliance with the criteria by the controller was built a system of hardware and software to perform some of the tests required by the standard. The performance of
the controller was designed compared to the controller pre-existing commercial incubator.
It was verified that the controller designed could meet the criteria of the standard more efficiently than the already pre existing business in the incubator.

▼ This work deals with an on-line control strategy based on Robust Model
Predictive Control (RMPC) technique applied in a real coupled tanks system.
This process consists of two coupled tanks and a pump to feed the liquid to the
system. The control objective (regulator problem) is to keep the tanks levels in
the considered operation point even in the presence of disturbance. The RMPC
is a technique that allows explicit incorporation of the plant uncertainty in the
problem formulation. The goal is to design, at each time step, a state-feedback
control law that minimizes a 'worst-case' infinite horizon objective function,
subject to constraint in the control. The existence of a feedback control law
satisfying the input constraints is reduced to a convex optimization over linear
matrix inequalities (LMIs) problem. It is shown in this work that for the plant
uncertainty described by the polytope, the feasible receding horizon state
feedback control design is robustly stabilizing. The software implementation of
the RMPC is made using Scilab, and its communication with Coupled Tanks
Systems is done through the OLE for Process Control (OPC) industrial protocol

A arquitetura de Sistema de Controle via Rede Sem Fio (WNCS) possui vantagens em relação à s arquiteturas tradicionais ponto-a-ponto e à s arquiteturas de redes cabeadas devido à facilidade de instalação, configuração e manutenção. No entanto, a evolução desta tecnologia introduziu novos desafios para a implementação da malha de controle fechada por um instrumento wireless como as não linearidades, perda de pacote de dados e restrições da comunicação de dados nas redes sem fio. Outro fator crÃtico relacionado à implementação de WNCSs é a fonte de energia limitada destes transmissores, que possuem vida útil dependente da quantidade de acessos e dados transmitidos. Este trabalho apresenta o estudo e o desenvolvimento de um controlador preditivo multi-rate como alternativa para melhorar a eficiência energética em aplicações industriais de WNCSs. A estratégia proposta não necessita receber constantemente os valores reais das variáveis do processo transmitidos pelos transmissores wireless, pois o controlador preditivo baseado em modelo (MPC) se utiliza do submodelo interno das variáveis de processo para estimar os valores das variáveis quando estas não são transmitidas. Dessa forma, uma diminuição da frequência de transmissão de dados na rede sem fio pode ser obtida e, consequentemente uma redução do consumo energético dos dispositivos sem fio. Resultados de simulações em diferentes condições de operação de um WNCS multivariável de controle de tanques acoplados demonstram que o MPC multi-rate possui caracterÃsticas de robustez e é efetivo para aplicações de WNCS, garantindo requisitos de controle e estabilidade mesmo com a diminuição da frequência de transmissão de dados de realimentação na rede sem fio. Adicionalmente, resultados do consumo energético dos dispositivos do WNCS mostraram que o MPC multi-rate proporciona uma economia de energia de até 20% das baterias dos transmissores wireless. Uma análise da eficiência energética do WNCS é apresentada através do estudo dos limites operacionais do controlador MPC multi-rate considerando a relação de compromisso entre o perÃodo de amostragem dos dispositivos sem fio e o desempenho de controle do WNCS.
Wireless communication technology has become a fundamental part of the everyday life of process industries, where the use of wireless transmitters for monitoring and control is already a reality. The architecture of Wireless Networked Control Systems (WNCSs) has advantages over point-to-point and wired networks architectures due to the ease of installation, configuration and maintenance. However, the evolution of this technology has introduced new challenges to the implementation of the closed loop control with a wireless instrument as nonlinearities, packet losses and data communication constraints in the wireless networks. Another critical factor related to implementation…

▼ The purpose of this Master Thesis concerns further development of ABB´s multivariable prediction controller 3dMPC.The product 3dMPC consists of both on-line and off-line components and controls a multivariable process by a combination of feedback and feed-forward. The Master Thesis involves two assignments: both of them deal with the engineering tool in off-line. One of the assignments was to to make a graphical tool to connect subsystems in the modeling tools in the engineering part of 3dMPC. The model connection algorithm handles cascade connections, i.e. output signals from one model are input signals to another model. State space models for the subsystems are used to create a state space model for the total system. When the total model is constructed, it can be saved to disk as a 3dMPC model file. Assignment number two handles another problem. A controlled multivariable process has normally a number of control signals and some output signals to be controlled, which here are assumed to be pre-defined. In addition to these signals, the 3dMPC has the ability to use other signals to improve the control. There are two types of additional signals: feed-forward signals, which are independent measurable input signals to the process, and measurable output signals from the process, which can be used to improve the estimation of the internal state of the process. In practice is it often hard to know both which measurable disturbances are worth considering, and which additional process variables that could be of any use. To determine the usefulness of these signals, models are identified containing different sets of signals. The scalar norm of the prediction quality of the state space models is calculated and compared. Thus the application assists in the determination of signals and proposes which signals the user should use when building the model to improve the control.
