▼ Grancreteâ„¢ is a novel cementitious material originally developed at Argonne National Laboratories and consist of a family of magnesium phosphate cement (
MPC) products. The objective of this thesis is to examine the basic characteristics of one type of Grancrete named Grancrete HFR (High Fire Resistant) which is basically a Fiber-Reinforced Magnesium Potassium Phospho-Silicate Cement. The research program included a comprehensive experimental program to evaluate the fundamental properties of the fresh mixture of Grancrete HFR paste, the mechanical properties of the hardened Grancrete HFR paste, and the bond characteristics of Grancrete HFR paste to selected construction materials.
The reaction of Grancrete HFR powder and water is exothermic. Test results indicate that the setting time of Grancrete HFR paste is less than 10 minutes, and the pH level of the fresh paste is close to 7. Typical values of Compressive Strength of the paste at 28 days range between 6,000 to 10,000 psi, and more than 50% of this strength was achieved within the first 24 hours of air curing. The measured ultimate strain ranges between 0.006 and 0.008. The Modulus of Elasticity is between 1650 and 1950 ksi. The Modulus of Rupture is approximately 1,100 psi and can be achieved after 3 days of air curing. Water absorption is less than 2%. The linear shrinkage is around 0.30%. Grancrete HFR has excellent bond strengths with itself, concrete and steel.

▼ Two parties, Alice and Bob, hold inputs x and y respectively. They wish to compute a function f of their inputs. In an ideal world, f (x, y) could be calculated by sending the inputs to a trusted third party. In the absence of such a third party, Alice and Bob are required to communicate directly. Alice would like the real-world computation of f to reveal no more about her input x to Bob than he could have deduced from the ideal-world interaction. In addition, Alice would like this guarantee to hold even if Bob cheats at the protocol. Bob would like the computation to have the same properties with regards to security against malicious Alice.
If both parties have unlimited computation power, such a feat is impossible for all but the simplest f . We introduce a trusted third party that can compute for Alice and Bob a different function g. If f can be computed in this modified model, we say that f reduces to g. Some g, which we call complete, have a special structural property that allows all f to reduce to g. These reductions are well-studied. Unfortunately, if g does not have this structural property, we do not fully understand reductions to g. This thesis describes our work in characterizing this landscape.
In particular, we show that if f reduces to g by some deterministic protocol or by a randomized protocol with a strict sub-logarithmic bound in the number of communication rounds, then we can shorten these protocols to use only a single call to g. In addition, we give a combinatorial property of f and g that is present if and only if this single-call protocol is possible. We also show an example of f and g where a randomized and potentially super-logarithmic protocol is required for f to reduce to g. This example hints at a direction for future investigation towards the complete characterization of these reductions.

▼ An adaptive model predictive control (MPC) method using models derived from orthonormal basis functions is presented. The defining predictor dynamics are obtained from state-space realizations of finite truncations of generalized orthonormal basis functions (GOBF). A structured approach to define multivariable system models with customizable, open-loop stable linear dynamics is presented in Chapter 2. Properties of these model objects that are relevant to the adaptation component of the overall scheme, are also discussed. In Chapter 3, non-adaptive model predictive control policies are presented with the definition of extended state representations through filter operations that enable output feedback. An infinite horizon set-point tracking policy which always exists under the adopted modeling framework is presented. This policy and its associated cost are included as the terminal stage elements for a more general constrained case. The analysis of robust stability guarantees for the non-adaptive constrained formulation is presented, under the assumption of small prediction errors. In Chapter 4, adaptation is introduced and the certainty equivalence constrained MPC policy is formulated under the same framework of its non-adaptive counterpart. Information constraints that induce the excitation of the signals relevant to the adaptation process are formulated in Chapter 5. The constraint generation leverages the GOBF model structure by enforcing a sufficient richness condition directly on the state elements relevant to the control task. This is accomplished by the definition of a selection procedure that takes into account the characteristics of the most current parameter estimate distribution. Throughout the manuscript, illustrative simulation examples are provided with respect to minimal plant models. Concluding remarks and general descriptions for potential future work are outlined in Chapter 6.

▼ Novel In Vitro Susceptibility Measurement of Vancomycin and Other Antibiotics Against Blood Isolates of Staphylococcus Aureus
Staphylococcus aureus is a versatile pathogen causing mild to moderate to severe and life threatening infections including blood stream infections. Methicillin resistant Staphylococcus aureus (MRSA) has evolved as an important nosocomial pathogen and multi-drug resistance limits the available antibiotics for therapy. In many healthcare facilities, vancomycin remains the preferred agent for treating serious MRSA infections; however, other drugs like linezolid and tedizolid are also useful agents. Tedizolid is a newly approved drug and currently only available for clinical use in some countries. Some data suggests that as the minimum inhibitory concentration (MIC) of vancomycin for MRSA increases beyond 2ug/ml, therapeutic failures become more common. We studied 60 blood culture of MRSA and determined MIC and mutant prevention concentration (
MPC) values to vancomycin, linezolid and tedizolid. In separate experiments, we preformed in vitro kill studies.
The minimum inhibitory concentration (MIC) is defined as the lowest drug concentration required to inhibit or block the growth of 105 colony forming units per milliliter (CFU/ml) of bacteria and is the international standard for determining susceptibility/resistance in clinical laboratories. The mutant prevention concentration (
MPC) defines the antimicrobial drug concentration blocking growth of the least susceptible cell present in high density (≥109 CFU) bacterial populations.
For vancomycin, MIC values ranged from 0.5 to 1.0ug/ml as compared to 1 – 4 µg/ml and 0.125 - 0.5 µg/ml for linezolid and tedizolid respectively. By
MPC testing, vancomycin
MPC values ranged from 2 to ≥32 µg/ml as compared to 2 – 4 µg/ml for linezolid and 0.25 – 0.5 µg/ml for tedizolid. Such high vancomycin
MPC values have not been previously reported. To further characterize strains showing high vancomycin
MPC values, we compared pulsed field gel electrophoresis (PFGE) profiles on strains with high vancomycin
MPC values to rule in or out, the presence of a single clone. A single clone was not detected. We also compared PFGE profiles on select strains with high vancomycin
MPC values to the profiles of the wild type (parental) strains and found the profiles were identical. Cell wall thickness of strains with high vancomycin
MPC values was investigated as a possible explanation of the higher
MPC values. For MRSA cells taken directly from agar plates containing high vancomycin drug concentrations, increased cell wall thickness was seen. Amplification of cell wall accessory genes by polymerase chain reaction (PCR) failed to identify a genetic marker that could explain the high
MPC values and the presence or absence of the Panton-Valentine leukocidin (PVL) gene was not more frequent in strains with high vancomycin
MPC values. Additionally, serial passage experiments increasing vancomycin drug concentrations did not result in a strain of MRSA with a stably resistant clone.…

▼ Gene therapy has the potential to treat a variety of
hereditary diseases such as diabetes, peanut anaphylaxis, cystic
fibrosis and different types of cancer. Gene therapy relies on the
design of a delivery system which can carry a gene of interest into
a cell. The delivery systems can be broken down into two different
types: viral and non-viral carriers. Viruses were the standard for
gene delivery and showed high cell transfection, but on the other
hand would sometimes induce an immunological response. As a result,
there has been a growing interest towards non-viral carriers such
as polymers which are less toxic and biocompatible.
Polyethyleneimine (PEI) is the current standard for non-viral gene
carriers, but has drawbacks such as high toxicity. The effect of
molecular weight and composition on transfection efficiency has
been evaluated for many polymers, but very few studies have been
done on polymer architecture. This study focused on the synthesis
of a hyperbranched phosphorylcholine cationic copolymer that
incorporates a nontoxic and biocompatible polymer known as
poly(2-Methacryoyloxyethyl Phosphorylcholine (MPC)). The
hyperbranched copolymers were synthesized via RAFT polymerization
through the incorporation of a cross linking agent and showed broad
molecular weight distributions. Complete binding to DNA was
achieved with the cationic polymers, however the gene expression
was found to be significantly lower than PEI when transfected into
Hep G2 cells. In the second part of this thesis, elastomer films
were embedded with conductive materials for potential
cardiovascular applications. Polydimethylsiloxane (PDMS) is an
elastomer used in a variety of medical applications because of its
biocompatibility. In this study, Poly(p-phenylene vinylene) (PPV)
and Multi-Walled Carbon Nanotubes (MWNT) which were two different
conductive materials, were embedded into PDMS and composite films
of PPV/PDMS and MWNT/PDMS were synthesized.

▼ Different model based control strategies are developed
for combustion timing and load control in a single cylinder
Homogeneous Charge Compression Ignition (HCCI) engine. In HCCI
engines, a lean homogeneous air-fuel mixture auto-ignites due to
compression and the resulting combustion occurs at lower
temperatures compared to spark ignition or diesel engines. The low
HCCI combustion temperatures result in low Nitrogen Oxides (NOX)
levels but high unburnt Hydrocarbons (HC) and Carbon Monoxide (CO)
levels. High HCCI thermal efficiency occurs when the combustion
efficiency is high and the combustion timing is appropriate. In
this thesis, the effects of fueling rate and valve timing on HCCI
engine performance and energy distribution are described. This
analysis indicates that Variable Valve Timing (VVT) with Symmetric
Negative Valve Overlap (SNVO) is an effective actuator for
combustion timing control. In addition, combustion timing affects
combustion efficiency which has an important role in engine energy
distribution. Next, a detailed multi-zone model with fuel specific
kinetics is developed for HCCI engine performance analysis that
captures valve timing and fueling rate dynamics. The multi-zone
physics based model has 483 states, 5 inputs and 4 outputs. PI
controller gains are first tuned using the detailed multi-zone
model in simulation and then the controller is implemented on a
single cylinder engine. Combustion timing is used as feedback to
the controller and valve timing is the main actuator. Then a
Feedforward/Feedback (Fdfwd/Fdbk) strategy is developed for HCCI
combustion timing control. The Fdfwd/Fdbk controller is based on a
model that relates combustion timing to valve timing and it is
combined with an integrator feedback to zero the steady state
error. A Model Predictive Control (MPC) strategy is then developed
for HCCI combustion timing and load control that takes into account
actuator and output constraints. A physics based approach is used
for model order reduction of the detailed multi-zone model and a
discrete nonlinear control oriented model is obtained with 4
states, 2 inputs and 2 outputs. This model is linearized around one
operating point and the MPC is designed based on the linearized
version of the 4-state control oriented model. The MPC is then
implemented on the single cylinder engine and the results are
compared to the PI and Fdfwd/Fdbk controller. The MPC exhibits good
tracking performance for combustion timing and load. Finally, a new
control oriented model is developed for combustion timing and load
control considering combustion efficiency. This model can be used
for future MPC design which consider combustion efficiency
constraints.

▼ This dissertation proposes a Limited-Communication Distributed Model Predictive Control algorithm for networks with constrained discrete-time linear processes as local subsystems. The introduced algorithm has an iterative and cooperative framework with neighbor-to-neighbor communication structure. Convergence to a centralized solution is guaranteed by requiring coupled subsystems with local information to cooperate only. During an iteration, a local controller exchanges its predicted effects with local neighbors (which are treated as measured input disturbances in local dynamics) and receives the neighbor sensitivities for these effects at next iteration. Then the controller minimizes a local cost function that counts for the future effects to neighbors weighted by the received sensitivity information. Distributed observers are employed to estimate local states through local input-output signals. Closed-loop stability is proved for sufficiently long horizons. To reduce the computational loads associated with large horizons, local decisions are parametrized by Laguerre functions. A local agent can also reduce the communication burden by parametrizing the communicated data with Laguerre sequences.
So far, convergence and closed-loop stability of the algorithm are proven under the assumptions of accessing all subsystem dynamics and cost functions information by a centralized monitor and sufficient number of iterations per sampling. However, these are not mild assumptions for many applications. To design a local convergence condition or a global condition that requires less information, tools from dissipativity theory are used. Although they are conservative conditions, the algorithm convergence can now be ensured either by requiring a distributed subsystem to show dissipativity in the local information dynamic inputs-outputs with gain less than unity or solving a global dissipative inequality with subsystem dissipativity gains and network topology only. Free variables are added to the local problems with the object of having freedom to design such convergence conditions. However, these new variables will result into a suboptimal algorithm that affects the proposed closed-loop stability. To ensure local
MPC stability, therefore, a distributed synthesis, which considers the system interactions, of stabilizing terminal costs is introduced. Finally, to illustrate the aspects of the algorithm, coupled tank process and building HVAC system are used as application examples.

▼ Vapor compression cooling systems are the primary method used for
refrigeration and air conditioning, and as such are a major component of household and
commercial building energy consumption. Application of advanced control techniques
to these systems is still a relatively unexplored area, and has the potential to significantly
improve the energy efficiency of these systems, thereby decreasing their operating costs.
This thesis explores a new method of decentralizing the capacity control of a
multiple evaporator system in order to meet the separate temperature requirements of
two cooling zones. The experimental system used for controller evaluation is a custom
built small-scale water chiller with two evaporators; each evaporator services a separate
body of water, referred to as a cooling zone. The two evaporators are connected to a
single condenser and variable speed compressor, and feature variable water flow and
electronic expansion valves. The control problem lies in development of a control
architecture that will chill the water in the two tanks (referred to as cooling zones) to a
desired temperature setpoint while minimizing the energy consumption of the system. A novel control architecture is developed that relies upon time scale separation of
the various dynamics of the system; each evaporator is controlled independently with a
model predictive control (
MPC) based controller package, while the compressor reacts
to system conditions to supply the total cooling required by the system as a whole.
MPC’s inherent constraint-handling capability allows the local controllers to directly
track an evaporator cooling setpoint while keeping superheat within a tight band, rather
than the industrially standard approach of regulating superheat directly. The compressor
responds to system conditions to track a pressure setpoint; in this configuration, pressure
serves as the signal that informs the compressor of cooling demand changes. Finally, a
global controller is developed that has knowledge of the energy consumption
characteristics of the system. This global controller calculates the setpoints for the local
controllers in pursuit of a global objective; namely, regulating the temperature of a
cooling zone to a desired setpoint while minimizing energy usage.

▼ Research Doctorate - Doctor of Philosophy (PhD)
This thesis develops control and modulation schemes for a multi-level H-bridge StatCom (HStatCom). The use of H-StatComs in high-power applications is increasing primarily due to the smaller footprint, higher achievable voltage levels, and ease of construction and maintenance of the device. However, there remain areas of research aimed at improving the performance of the topology. With improved performance and lower cost, the H-StatCom will find increasing application in both the medium and high voltage networks, and become an integral component in the distributed generation landscape. The practical performance of the industry standard modulation technique for H-StatComs is explored. It is shown that subtle implementation issues degrade the harmonic performance of this scheme. It is then observed that the existing modulation technique does not consider the large amounts of redundancy in the available switching states for the topology. Given this observation, the main contribution of this thesis is to develop a variation on a typical model predictive control scheme. The scheme can exploit the switching redundancy to simultaneously balance the H-bridge capacitor voltages, provide excellent current reference tracking and minimise converter switching losses. Finally, experimental and simulation results are presented that confirm the validity of the new strategy. The results show that model predictive control exceeds the performance of well established modulation schemes and provides extra flexibility to optimise user-defined key performance indicators.

▼ The world population is growing rapidly and the demand for healthy food grows with it. Greenhouse cultivation provides an efficient way to grow crops in a protected and controlled environment. In the past, many greenhouse control algorithms have been developed. How- ever, the majority of these algorithms rely on an explicit parametric model description of the greenhouse. These models are often based on physical laws such as conservation of mass and energy and contain many parameters which should be identified. Due to the complex and highly non-linear dynamics of greenhouses, these models might not be applicable to control greenhouses other than the one for which the model has been designed and identified. Hence, in current horticultural practice these control algorithms are scarcely used. Therefore, the need rises for a control algorithm which does not rely on a parametric system representa- tion but rather on input/output data of the greenhouse system, hereby establishing a way to control the system with unknown or unmodeled dynamics. A recently proposed algo- rithm, Data-Enabled Predictive Control (DeePC), is able to replace system identification, state estimation and future trajectory prediction by one single optimization framework. The algorithm exploits a non-parametric model constructed solely from input/output data of the system. This algorithm is employed in order to control the greenhouse climate. It is shown that in numerical simulation the DeePC algorithm is able to control the greenhouse climate. A comparison is made with the conventional Nonlinear Model Predictive Control (NMPC) algorithm in order to show the differences between a predictive control algorithm that has direct access to the non-linear greenhouse simulation model and a purely data-driven predic- tive control algorithm. Both algorithms are compared based on reference tracking accuracy and computational time. Furthermore, it is shown in numerical simulation that the DeePC algorithm is able to cope with changing dynamics within the greenhouse system throughout the crop cycle.

▼ Small-scale 3D-printing has become a common appearance. Today there are many companies specialized in selling and designing small-scale 3D-printers . Applications range from creating custom-made toys to creating spare parts for the 3D-printer itself as well as medical applications such as skull parts, knee replacements and hip replacements. The research and development start-up company HB|3D uses a 6 degrees-of-freedom robotic arm combined with a plasticating single-screw extruder and heated hose to create large-scale thermoplast products. One challenge is to scale up the 3D-printing process while ensuring a high-quality product. Feedback control looks promising in increasing the dimensional accuracy of large-scale printed objects by influencing the screw speed to minimize flow disruptions. The goal is to create a simulation of a model predictive controller and show that an output flow trajectory can be tracked within 1 percent accuracy. The flow response is modeled using a commercially available computational fluid dynamics software package (ANSYS FLUENT Academic Research version 18.1). This computationally intensive model is simplified using system identification techniques; resulting in a wiener model. Finally, a simulation of using a model predictive controller to track an output flow reference signal is then performed.

▼ Fast depleting fossil fuels and growing awareness for environmental protection have led us to the urgency of a long-term energy planning where reduction of emissions, integration of renewable supply, and energy efficiency improvement represent the main targets of a ‘smarter’ employment of primary resources. Research is needed nowadays to drive a transient phase towards the construction of future ‘smart grids’, where multiple actors will be able to communicate with each other and efficiently adapt their production/consumption with respect to the dynamic evolution of the increasingly complex power network. In this scenario, operational management of small, local electricity networks (microgrids) and their two-way interconnection to the main grid are creating new opportunities and, at the same time, new technological challenges. Advanced control schemes are being investigated to smoothen the integration of distributed generation and to achieve optimal operation at microgrid level, through coordination and dispatching of power generation, flexible loads, and storage elements. The residential sector is responsible for about 30% of the global energy consumption and has historically played a passive role in the unidirectional centralised power infrastructure. A residential microgrid that utilises controllable prime movers, such as gas engines, to compensate fluctuating demand and output of renewable energy would represent a fundamental step towards a more economic, efficient, and environment friendly energy infrastructure. This MSc thesis project focuses on the design of energy management systems in residential buildings where micro-Combined Heat and Power (CHP) generators are installed. Micro-CHP technology is able to produce electrical energy locally in a controllable way, having at the same time the advantage of efficiently employing by-product heat to satisfy thermal demand of the building where it is located. The purpose of our work is an economic analysis regarding the profitability of investment in distributed energy resources for Dutch households and a subsequent investigation about the benefits that advanced control techniques would lead to microgrid operation on the long run. For this reason, specific case studies are built based on real data of thermal and electric consumption, which have been collected through smart meters in various Dutch houses. Two different versions of the microgrid are considered: a first case only involves micro-CHP and thermal energy storage, whereas a second one is expanded to include solar panels. Advanced techniques employed for supervisory control of power flows in microgrids generally aim to take into account relevant information about the consequences of choosing specific actions, by considering future predictions of system evolution. Model Predictive Control (
MPC) is a well-known, established and widely used control technique that is often considered as a natural approach to adopt in microgrids. Its main strength is the ability to turn a control problem into an optimisation…

▼ Magnetic levitation is a recent technology which nowadays is used in high-tech systems. It is developed due to the inherent benefits of these type of setups such as lack of wear, friction and problems due to mechanical phenomenon as play and backlash. Achieving higher accelerations and ultra-precise position control while reducing maintenance. At Owl Tech the goal is to develop a magnetic levitation system capable of six-degrees-of-freedom motion to be employed in positioning systems, such as a 3D-printer, for the consumer market. The system consists of an array of electromagnets with an iron core which by controlling the current through each can shape a magnetic field. The magnetic field is manipulated to levitate and position a platform with permanent magnets in six-DoF. In previous research, the equations of motions for the platform have been derived. The equations of motion are a linearized version of the rigid body dynamics, allowing for translations and tiny rotations, subjected to external forces such as gravity, actuation and attraction forces. The actuation and attraction forces are non-linear with respect to the location of each permanent magnet. Finite element modeling was used to derive models for these forces with respect to the magnet location. To measure the location of the moving platform an array of 36 Hall-effect sensors is employed. The output of each sensor is combined and through sensor fusion with an extended Kalman filter using an experimental measurement model the platform location is determined. The proposed extended Kalman filter of previous research is compared with an approach based on real-time optimization and a linear Kalman filter. With as argument that the EKF has no theoretical guarantee to converge and might give biased results whereas the optimization algorithm has guaranteed convergence towards to magnet location. The localization algorithm is tested on the real system employing a positioning system. The positioning system performs a stroke while the algorithm is tracking the position. Resulting in an estimation accuracy error of /pm 1 mm while the precision error is /pm 0.1 mm. The proposed control architecture of previous research consists of a feedback control loop based on a non-linear output mapping. The non-linear output mapping decouples the coupled input currents after which each degree of freedom can be controlled separately by single-input-single-output state feedback controllers. In this research, a model predictive controller is proposed instead. A model predictive controller can deal with constraints inherently. Therefore it is capable of dealing with actuator saturation which would destabilize the system in the control architecture of previous research. Additionally, the
MPC architecture is extended to the so-called tube-based model predictive control to achieve a robust model predictive controller. Both control architectures are implemented in simulations and the real-system limited in two…

▼ With the growing penetration of plug-in electric
vehicles (PEVs), the impact of the PEV charging brought to the
utility grid draws more and more attention. This thesis focused on
the optimization of a home energy management system (HEMS) with the
presence of PEVs. For a household microgrid with photovoltaic (PV)
panels and PEVs, a HEMS using model predictive control (MPC) is
designed to achieve the optimal PEV charging. Soft electric loads
and an energy storage system (ESS) are also considered in the
optimization of PEV charging in the MPC framework. The MPC is
solved through mixed-integer linear programming (MILP) by
considering the relationship of energy flows in the optimization
problem. Through the simulation results, the performance of
optimization results under various electricity price plans is
evaluated. The influences of PV capacities on the optimization
results of electricity cost are also discussed. Furthermore, the
hardware development of a microgrid prototype is also described in
this thesis.

▼ Spacecraft formation flying offers many advantages in the form of cost, functionality, and performance. Future missions involving spacecraft formation flying will require high levels of control and a focus towards autonomy. One of the simplest cases of spacecraft formation flying is the reconfiguration problem which involves two satellites, a chief and a deputy, at an initial relative orbit and the goal is to reach a desired relative orbit. Model Predictive Control (
MPC) also known as Receding Horizon Control has been effective in the energy and petroleum industries and shows great promise in aerospace applications. This thesis explores the usage of
MPC with an application in this reconfiguration problem. The performance of the
MPC strategy is assessed with a comparison to a known piece-wise continuous analytical control solution. The
MPC controller was found to drive the Relative Orbital Elements (ROE) state within the same two-norm error of 0.2 in ROE state as the analytical control strategy, but with more total control cost. This shows that the
MPC strategy is a valid and useful controller for spacecraft formation flying. ( en )

▼ This dissertation proposes and, using simulation, analyzes control algorithms and their use on helicopter shipboard operations. Various benefits and advances for controls in this area are suggested, tested, and discussed. The control methods presented and implemented, while not limited to these use cases, are particularly well suited for them. One control algorithm is used for controlling flight near the landing point on a ship and performing a soft touchdown on the ship. The algorithm is tested in simulation. Another algorithm is used to control a helicopter initially in flight far away from the ship to slowly transition to stable flight near the ship, holding a rough position relative to the ship indefinitely at the end. This control could be used to set up the helicopter for later use of the touchdown control. This control is also tested in simulation. A method of quantifying what conditions the touchdown controller has a relatively good chance of successfully landing in is then suggested. The range of conditions for which successful touchdown has a relatively high chance of being achieved along with an analysis of that likelihood is called the landing envelope. Using the landing envelope construction method with numerous simulations, a landing envelope for the touchdown controller is obtained. The touchdown controller assumes that the helicopter’s dynamics are linear. Helicopter dynamics (like most dynamics of real systems) are nonlinear. However, under conditions near the point that dynamics are linearized about, a linear approximation is sufficiently accurate. To improve on the above landing algorithm, a method of combining multiple specific implementations of the touchdown controller to help account for nonlinearity to improve the approximation of the dynamics that the controller assumes is then suggested and performed in simulation.

▼ With the proliferation of small-scale solar PV installations, global horizontal irradiance (GHI) and power predictions are becoming critical elements in the integration of PV generation into the grid. This thesis considers short-term prediction, from minutes to hours, based on historical meteorological measurement data from weather and power monitoring stations located in the Canberra (Australia) region. The specific objective of this study is to produce accurate forecasts for (a generic) target station using a minimal amount of observations from nearby stations. Thus, although a large number of weather and power variables were collected and used for developing and testing the prediction algorithms, the ultimate aim is to rely on a few predictors, mainly meteorologically based. This will allow the identification of critical instruments which would need to be installed in order to provide satisfactory PV power predictions while limiting capital and operating costs of monitoring. Relative mean absolute error (rMAE) is used to indicate prediction performance. Three statistical methods are tested for two different seasons, winter and summer. The relative importance of predictors and stations is assessed. A conversion from GHI to global irradiance on tilted surfaces, by means of simple geometry arguments and notion of irradiance components at a nearby site, is also introduced and tested. Finally, the prediction accuracy is categorised according to different clear-sky indecs. Results show that when the clear-sky index exceeds 0.9 (near-to-cloudless conditions), the prediction performance is distinctly better than at lower clear sky indices which are under 0.9, by at least 0.05 and 0.2 in terms of rMAE in summer and winter, respectively. The second contribution of this thesis is a standalone PV-Battery hybrid system and the solar irradiance anticipation is used as simulation input to PV panels. There are two converters in the hybrid model. The unidirectional DC-DC converter, which is linked between PV panels and DC bus for power supply, works under maximum power point tracking (MPPT) mode, while the other, the bidirectional DC-DC converter located between battery banks and DC bus, operates under a model predictive control (
MPC) algorithm. By charging and discharging the battery, the voltage of the DC bus can be kept in a certain range to meet the load requirement.

▼ Aerial cinematography has seen an increased use of Unmanned Aerial Vehicle (UAV) due to technological advancements and commercialisation in recent years. The operation of such a robot can be complex and requires a dedicated person to control it. Automation of the cinematography allows for the use of multiple robots, which further increases the complexity of performing cinematography. High-level command interpretation is required to allow for an intuitive interface suited for an inexperienced user to control such a system. Natural Language (NL) is an intuitive interface method which allows a user to specify a extensive range of commands. A Cinematographic Description Clause (CDC) is defined to extract information from a processed NL command. A minimum input approach is considered such that a user has to merely specify the number of robots and the people to record, whereby the specification of a behaviour is optional. An environment is considered in which up to three robots have to frame two people. Taking into account their orientation, relative global location and the user command, a set of behaviours can be determined based on cinematographic practices. Camera views and image parameters are determined through behaviour specific non-linear optimisations and assigned to the robots using a Linear-Bottleneck Algorithm (LBA). A collision-free global path is computed for each robot with an A* search algorithm. Finally, a Model Predictive Control (MPC) determines low-level inputs such that the user command can be achieved. Three situations are considered to validate the performance of the system given the minimal user input. First, tracking of the dynamic orientations of the people is evaluated for up to three robots, whereby camera positions are determined autonomously. Next, dynamic motions of the two people through an environment highlight the limitations of the system due to collision mitigation, mutual visibility and robot dynamics. An extension to multiple simultaneous commands increases the quantity of robots and people that can be tracked. This allows for an assessment of the flexibility and scalability of the proposed high-level command interpretation methodology.

▼ The work in this thesis focuses on the development of a Stochastic Model Predictive Control (SMPC) algorithm for linear systems with additive and multiplicative stochastic uncertainty subjected to linear input/state constraints. Constraints can be in the form of hard constraints, which must be satisfied at all times, or soft constraints, which can be violated up to a pre-defined limit on the frequency of violation or the expected number of violations in a given period. When constraints are included in the SMPC algorithm, the difficulty arising from stochastic model parameters manifests itself in the online optimization in two ways. Namely, the difficulty lies in predicting the probability distribution of future states and imposing constraints on closed loop responses through constraints on predictions. This problem is overcome through the introduction of layered tubes around a centre trajectory. These tubes are optimized online in order to produce a systematic and less conservative approach of handling constraints. The layered tubes centered around a nominal trajectory achieve soft constraint satisfaction through the imposition of constraints on the probabilities of one-step-ahead transition of the predicted state between the layered tubes and constraints on the probability of one-step-ahead constraint violations. An application in the field of Sustainable Development policy is used as an example. With some adaptation, the algorithm is extended the case where the uncertainty is not identically and independently distributed. Also, by including linearization errors, it is extended to non-linear systems with additive uncertainty.

▼ Ce manuscrit de thèse s'intéresse à la modélisation et au contrôle des réfrigérateurs cryogéniques. Le cas particulier des réfrigérateurs soumis à de fortes variations de charges thermiques est étudié. Un modèle de chaque objet pouvant se trouver dans un réfrigérateur est proposé. La méthodologie d'assemblage pour obtenir le modèle des sous-systèmes qui composent le réfrigérateur est présenté, accompagnée de la méthode permettant d'obtenir une approximation linéaire des modèles des sous-systèmes. Grâce aux modèles développées, des lois de commande avancées sont synthétisées. Un contrôleur linéaire quadratique pour les stations de compression à deux ou trois niveaux de pression est proposé, ainsi qu'un contrôleur prédictif sous contrainte pour la boite froide. La particularité de ces stratégies de contrôle est qu'elles sont compatibles avec un automate programmable industriel (API) , doté d'une capacité de calcul et de stockage de donnée réduite. La capacité de prédiction en boucle ouverte du modèle développé est validé au regard de données expérimentales et les stratégies de contrôle sont validés en simulation et expérimentalement sur la station d'essais [email protected] du SBT et sur la station de compression du LHC, au CERN.
This manuscript is concern with both the modeling and the derivation of control schemes for large cryogenic refrigerators. The particular case of those which are submitted to highly variable pulsed heat load is studied. A model of each objet that normally compose a large cryorefrigerator is proposed. The methodology to gather objects model into the model of a subsystem is presented. The manuscript also shows how to obtain a linear equivalent model of the subsystem. Based on the derived models, advances control scheme are proposed. Precisely, a linear quadratic controller for warm compression station working with both two and three pressures state is derived, and a predictive constrained one for the cold-box is obtained. The particularity of those control schemes is that they fit the computing and data storage capabilities of Programmable Logic Controllers (PLC) with are well used in industry. The open loop model prediction capability is assessed using experimental data. Developed control schemes are validated in simulation and experimentally on the [email protected] SBT's cryogenic test facility and on the CERN's LHC warm compression station.

▼ Real-time optimization (RTO) is a supervisory strategy in the hierarchical industrial process automation architecture in which economically optimal set-point targets are computed for the lower level advanced control system, which is typically model predictive control (
MPC). Due to highly volatile market conditions, recent developments have considered transforming the conventional steady-state RTO to dynamic RTO (DRTO) to permit economic optimization during transient operation. Published DRTO literature optimizes plant input trajectories without taking into account the presence of the plant control system, constituting an open-loop DRTO (OL-DRTO) approach. The goal of this research is to develop a design framework for a DRTO system that optimizes process economics based on a closed-loop response prediction. We focus, in particular, on DRTO applied to a continuous process operation regulated under constrained
MPC. We follow a two-layer DRTO/
MPC configuration due to its close tie to the industrial process automation architecture.
We first analyze the effects of optimizing
MPC closed-loop response dynamics at the DRTO level. A rigorous DRTO problem structure proposed in this thesis is in the form of a multilevel dynamic optimization problem, as it embeds a sequence of
MPC optimization subproblems to be solved in order to generate the closed-loop prediction in the DRTO formulation, denoted here as a closed-loop DRTO (CL-DRTO) strategy. A simultaneous solution approach is applied in which the convex
MPC optimization subproblems are replaced by their necessary and sufficient, Karush-Kuhn-Tucker (KKT) optimality conditions, resulting in the reformulation of the original multilevel problem as a single-level mathematical program with complementarity constraints (MPCC) with the complementarities handled using an exact penalty formulation. Performance analysis is carried out, and process conditions under which the CL-DRTO strategy significantly outperforms the traditional open-loop counterpart are identified.
The multilevel DRTO problem with a rigorous inclusion of the future
MPC calculations significantly increases the size and solution time of the economic optimization problem. Next, we identify and analyze multiple closed-loop approximation techniques, namely, a hybrid formulation, a bilevel programming formulation, and an input clipping formulation applied to an unconstrained
MPC algorithm. Performance analysis based on a linear dynamic system shows that the proposed approximation techniques are able to substantially reduce the size and solution time of the rigorous CL-DRTO problem, while largely retaining its original performance. Application to an industrially-based case study of a polystyrene production described by a nonlinear differential-algebraic equation (DAE) system is also presented.
Often large-scale industrial systems comprise multi-unit subsystems regulated under multiple local controllers that require systematic coordination between them. Utilization of closed-loop prediction in the CL-DRTO…

▼ The main topic of this thesis is model predictive control (MPC) of an unstable fighter aircraft. When flying it is important to be able to reach, but not exceed the aircraft limitations and to consider the physical boundaries on the control signals. MPC is a method for controlling a system while considering constraints on states and control signals by formulating it as an optimization problem. The drawback with MPC is the computational time needed and because of that, it is primarily developed for systems with a slowly varying dynamics. Two different methods are chosen to speed up the process by making simplifications, approximations and exploiting the structure of the problem. The first method is an explicit method, performing most of the calculations offline. By solving the optimization problem for a number of data sets and thereafter training a neural network, it can be treated as a simpler function solved online. The second method is called fast MPC, in this case the entire optimization is done online. It uses Cholesky decomposition, backward-forward substitution and warm start to decrease the complexity and calculation time of the program. Both methods perform reference tracking by solving an underdetermined system by minimizing the weighted norm of the control signals. Integral control is also implemented by using a Kalman filter to observe constant disturbances. An implementation was made in MATLAB for a discrete time linear model and in ARES, a simulation tool used at Saab Aeronautics, with a more accurate nonlinear model. The result is a neural network function computed in tenth of a millisecond, a time independent of the size of the prediction horizon. The size of the fast MPC problem is however directly affected by the horizon and the computational time will never be as small, but it can be reduced to a couple of milliseconds at the cost of optimality.

▼ In this thesis, the main focus is on the design and implementation of an advanced control scheme, namely model predictive control (MPC) to the grid- connected voltage source converter (VSC) for a three phase system. MPC is a control paradigm that solves a mathematical optimization problem based on a dynamic model of the system. Due to the computationally demanding nature of MPC, the areas of applications have long been restricted to slow dynamical systems. However, with the recent advancement of microprocessor and simu- lation technologies, application of MPC is now even possible for the control of power electronics. With a very powerful concept such as on-line cost optimisation, input/output constraint handling and model-based design, MPC is able to offer the optimal actuation that allows one to achieve very fast dynamics, while also considering uncertainties such as system parameter variations and unknown disturbances. Furthermore, it is also possible to take advantage of the discrete nature of the power converters and choose from the possible switching states the optimal solution according to the minimization of a predefined cost. Â Exploring these advantages of MPC and making them suitable for the control of power converters are the key focus of the thesis. The first part of the thesis investigates a multi-variable control scheme, namely a predictive voltage controller that controls both DC bus voltage and re- active current (i.e. q-axis current) in the synchronous reference frame. Explicit tuning methods of MPC are introduced to improve the closed-loop transient response as well as improving the robustness against the parameter variations such as the grid inductance. The second part of the thesis focuses on the predictive current control design. A predictive current controller for VSC with LCL (inductor-capacitor- inductor) input filter is first proposed with a robust control scheme that employs nominal and disturbance rejection control parts. The nominal control part is designed using the reduced-order model (i.e. L filter model) to control dominant dynamics of the LCL filter where as the disturbance rejection control part actively suppresses the disturbance due to unmodeled dynamics of LCL filter (i.e. resonance of the LCL filter). Following from this, a predictive resonant controller is presented to control the converter in the stationary frame axis. A resonant module with a grid frequency is embedded in the model to handle the periodicity in the measured states and the reference inputs. The proposed de- sign considers the periodic input constraints in the stationary frame as well as disturbances due to grid voltage distortion. The last part of the thesis investigates the stability aspect of a finite control set predictive control (FCS-MPC) method and presents a design framework to handle the imposed the output current constraints in the cost function. All of the presented control methods in this thesis are experimentally validated on a 1kW prototype converter that has been built by the author.

▼ Linear model predictive control has been widely accepted in industry as an important tool for the operation of difficult interacting processes. Linear identification and control techniques are well developed and well understood. In the industry, it is rare to find a system that is truly linear. While for many systems linear modeling and control can approximate their performance in certain regions, there exist some systems whose nonlinearity is great enough that an approximate linear model and control scheme cannot yield the desired accuracy. In order to control these more complex nonlinear systems, significant research has been dedicated to extending model predictive control to nonlinear systems.

▼ A dynamic real-time optimization (DRTO) formulation with closed-loop prediction is used to coordinate distributed model predictive controllers (MPCs) by rigorously predicting the interaction between the distributed MPCs and full plant response in the DRTO formulation. This results a multi-level optimization problem and that is solved by replacing the MPC quadratic programming subproblems by their equivalent Karush-Kuhn-Tucker (KKT) first-order optimality conditions to yield a single-level mathematical program with complementarity constraints (MPCC). The proposed formulation is able to perform both target tracking and economic optimization with significant performance improvement over decentralized control, and similar performance to centralized MPC. A linear dynamic case study illustrates the performance of the proposed strategy for coordination of distributed MPCs for different levels of plant interaction,. The method is thereafter applied to a nonlinear integrated plant with recycle, where its performance in both set-point target tracking and economic optimization is demonstrated.
Subsequently, this study presents two techniques for approximation of the closed-loop prediction within the DRTO formulation - a hybrid closed-loop formulation and an input clipping formulation. The hybrid formulation generates closed-loop predictions for a limited number of time intervals along the DRTO prediction horizon, followed by an open-loop optimal control formulation extended to rest of the horizon. The input clipping formulation utilizes an unconstrained MPC optimization formulation for each distributed MPC, coupled with the application of an input saturation mechanism. The performance of the approximation techniques is evaluated through application to case studies based on linear and nonlinear dynamic plant models respectively. The approximation techniques are demonstrated to be more computationally efficient than than the rigorous counterpart without significant loss in performance.
The performance of the proposed DRTO formulation can be further improved by the introduction of nonlinearity. The nonlinear dynamic plant model is firstly introduced in the DRTO formulation while maintaining the linear formulation for the distributed MPCs. The performance of resulting formulation is demonstrated and compared against the linear counterpart. The nonlinear MPC formulation is then included in both lower-level control implementation and DRTO formulation. By reformulating the Lagrangian of the nonlinear MPC optimization subproblems, the nonlinear MPC formulation is successfully implemented in the DRTO formulation. The performance of such DRTO formulation is further improved and shown using a nonlinear case study.
The conclusion of this study is summarized and the potential directions of this research such as large-scale applications, variation of MPC implementations, and robust model-based control are outlined and explained in the end.

▼ Masters Research - Master of Philosophy (MPhil)
This thesis deals with the need to reduce the electricity demand in induction heating processes, in particular those used in the steel industry where a large amount of electrical energy is used. Current practices are almost entirely based on open loop schemes where the surface temperature of steel rods is the main target. No consideration is given to energy efficiency. A human operator controls manually the power setting to the electronic converters to modify the rod temperature and therefore the use of electricity. New techniques to reduce the energy demand based on a combination of traditional open-loop strategies and novel closed-loop control are developed in this thesis and some industrial experiments are carried out. The proposed techniques include closed loop strategies such as non-linear model predictive control and off-line optimizations. Some of them are presented from a theoretical perspective while a few of them could be implemented in the industrial environment. The need of a large industrial facility of several Mega Watts to test the improvements implied that only a few number of trials could be implemented. One of the off-line optimizations carried out in this thesis consisted in seeking the best balance of power across an induction heating process formed by two furnaces. The modification of this power balance resulted in a saving in energy whilst satisfying all the metallurgical constrains of the process described in details in Chapter 3. Indeed for the studied process, our results show that a saving range of 2% to 5% can be achieved according to the production conditions. It is believed that a combination of several techniques described in this thesis has the potential to reduce the energy in more than 10 % when compared to a traditional open loop strategy. Future work will be aimed at customizing the methodologies towards full industrial implementation of closed loop control.

▼ One of the major challenges that building owners and operators face is maintaining a low cost of operation. In certain markets within the U.S., electrical cost varies throughout the day; it is higher during times of peak demand. This leaves the customer the incentive to cut back electrical use during peak demand periods. Since 40% of the peak electrical demand is due to the operation of the building HVAC system alone, the opportunity exists for shifting the building cooling load to off-peak hours. This can be done by pre-cooling the space, thereby using the building mass as a sort of thermal battery, which can then discharge later, alleviating the cooling load off the HVAC system during peak times. It is in this thesis that a peak load reduction strategy is presented using model predictive control (
MPC). Furthermore, the system modeled in this paper is a two-zone system, each having a dedicated controller. First the problem is explored with a single, centralized
MPC which calculates the optimal trajectory for the entire building. Secondly, the load reduction strategy control is distributed to each individual controller. The advantage to distributed control is the reduction of computing resources which brings with it a cost reduction on its own. Lastly, both
MPC approaches are compared to the traditional PI-only control scheme. Results showed that the distributed scheme proved favorable next to the centralized
MPC benchmark, and both
MPC approaches produced favorable results over the traditional PI-only control.
