▼ Many engineering systems – including electrical power networks, chemical processing plants, and communication networks – have a well-defined notion of an "optimal'" steady-state operating point. This optimal operating point is often defined mathematically as the solution of a constrained optimization problem that seeks to minimize the monetary cost of distributing electricity, maximize the profit of chemical production, or minimize the communication latency between agents in a network. Optimal steady-state regulation is obviously of crucial importance in such systems. This thesis is concerned with the optimal steady-state control problem, the problem of designing a controller to continuously and automatically regulate a dynamical system to an optimal operating point that minimizes cost while satisfying equipment constraints and other engineering requirements, even as this optimal operating point changes with time. An optimal steady-state controller must simultaneously solve the optimization problem and force the plant to track its solution. This thesis makes two primary contributions. The first is a general problem definition and controller architecture for optimal steady-state control for nonlinear systems subject to time-varying exogenous inputs. We leverage output regulation theory to define the problem and provide necessary and sufficient conditions on any optimal steady-state controller. Regarding our controller architecture, the typical controller in the output regulation literature consists of two components: an internal model and a stabilizer. Inspired by this division, we propose that a typical optimal steady-state controller should consist of three pieces: an optimality model, an internal model, and a stabilizer. We show that our design framework encompasses many existing controllers from the literature. The second contribution of this thesis is a complete constructive solution to an important special case of optimal steady-state control: the linear-convex case, when the plant is an uncertain linear time-invariant system subject to constant exogenous inputs and the optimization problem is convex. We explore the requirements on the plant and optimization problem that allow for optimal regulation even in the presence of parametric uncertainty, and we explore methods for stabilizer design using tools from robust control theory. We illustrate the linear-convex theory on several examples. We first demonstrate the use of the small-gain theorem for stability analysis when a PI stabilizer is employed; we then show that we can use the solution to the H-infinity control problem to synthesize a stabilizer when the PI controller fails. Furthermore, we apply our theory to the design of controllers for the optimal frequency regulation problem in power systems and show that our methods recover standard designs from the literature.

▼ Robust control is an aspect of control theory which explicitly considers uncertainties and how they affect robust stability in the analysis and design of control decisions. A basic requirement for optimal robust guaranteed control in a real life scenario is the stabilization of systems in the presence of uncertainties or perturbations. In this thesis, the system uncertainties are embedded into a norm bounded uncertainty elements. The perturbation function is modelled as a class of nonlinear uncertainty influencing a neutral system with infinite delay. It is assumed to have delay in state and is input dependent; which implies the effect of control action can directly or indirectly influence the nonlinear perturbation function. In recognition of the fact that stability and controllability are fundamental in obtaining the optimal robust guaranteed cost control design for neutral functional integro-differential systems with infinite delays (NFDSID), total asymptotic stability results were developed using Razumikhin technique, unique properties of eigenvalues, and the uniform stability properties of the functional difference operator for neutral systems. The new results, obtained using Razumikhin’s technique, extend and complement basic stability results in neutral systems to NFDSID. Novel sufficient conditions were developed for the null controllability of nonlinear NFDSID when the controls are constrained. By exploring the knowledge gained through other controllability results; conditions are placed on the perturbation function. This guaranteed that, if the uncontrolled system is uniformly asymptotically stable, and the controlled system satisfies a full rank condition, then the control system is null controllable with constraint if it satisfies some algebraic conditions. The investigation of optimal robust guaranteed cost control method has resulted in a novel delay dependent stability criterion for a nonlinear NFDSID with a given quadratic cost function. The new design is based on a model transformation technique, Lyapunov matrix equation and Lyapunov-Razumikhin stability approach. The Lyapunov-Razumikhin technique is adopted for this investigation because it is considered more scalable for optimal robust guaranteed cost control design for NFDSID. It is demonstrated that a memory less feedback control can be synthesized appropriately to ensure: (i) the closed-loop systems robust stability, and (ii) guarantee that the closed-loop cost function value remains within a specified bound. The problem of designing the optimal guaranteed cost controller is also realized in terms of inequalities. The Lyapunov-Krasovskii method is used to obtain stability conditions in comparison to the Razumikhin method. This method leads to linear matrix inequality (LMI) for the delay-independent case which is known to be conservative. To illustrate the potential practical applicability of the theoretical results; a cascade connection of two fully filled chemical solution mixers, and an integrated lossless transmission line which has a…

▼ Recent progress in communication technologies and their use in feedback control systems motivate to look deeper into the interplay of control and communication in the closed-loop feedback architecture. Among several research directions on this topic, a great deal of attention has been given to the fundamental limitations in the presence communication constraints. Entropy rate inequalities corresponding to the information flux in a typical causal closed loop have been derived towards obtaining a Bode-like integral formula. This work extends the discrete-time result to continuous-time systems. The main challenge in this extension is that Kolmogorov's entropy rate equality, which is fundamental to the derivation of the result in discrete-time case, does not hold for continuous-time systems. Mutual information rate instead of entropy rate is used to represent the information flow in the closed-loop, and a limiting relationship due to Pinsker towards obtaining the mutual information rate between two continuous time processes from their discretized sequence is used to derive the Bode-like formula. The results are further extended to switched systems and a Bode integral formula is obtained under the assumption that the switching sequence is an ergodic Markov chain. To enable simplified calculation of the resulting lower bound, some Lie algebraic conditions are developed. Besides analysis results, this dissertation also includes joint control/communication design for closed-loop stability of performance. We consider the stabilization problem within Linear Quadratic Regulator framework, where a control gain is chosen to minimize a linear quadratic cost functional while subject to the input power constraint imposed by an additive Gaussian channel which closes the loop. Also focused on Gaussian channel, the channel noise attenuation problem is addressed, by using H-infinity/H2 methodology. Similar feedback optimal estimation problem is solved by using Kalman filtering theory. Advisors/Committee Members: Hovakimyan, Naira (advisor), Hovakimyan, Naira (Committee Chair), Kumar, P. R.

▼ This project was started as a result of strict environmental and health regulations together with a demand tor cost effective operation of wastewater treatment plants (VVWTPs). The main aim of this project is how to keep effluent concentration below a prescribed limit at the lowest possible cost. Due to large fluctuations in the quality and quantity of the influent concentrations, traditional control methods are not adequate to achieve this aim The major drawback with these methods is that the disturbances affect the process before the controller has time to correct the error (Olsson and Newell, 1999: 454). This problem is addressed through the use of modern control systems. Modern control systems are model based predictive algorithms arranged as feed-forward controllers (Olsson and Newell. 1999: 454). Normally a controller is equipped with a constant set point; the goal In this project is to calculate an optimal DO trajectory that may be sampled to provide a varying optimal set-point for the Activated Sludge Process, In this project an optimal control problem Is formulated using DO concentration as a control variable. This requires a model of the process to be controlled a mathematical expressions of the limitations on the process input and output variables and finally the objective functional. which consists of the objectives of the control. The structures of the Benchmark plant (developed within the COST 682 working group) and the Athlone WWTPs are used to implement this opt.mat control strategy in MATLAB. The plant's full models are developed based on the mass balance principle incorporating the activated sludge biological models: ,ASM1, ASM2, ASM2d and ASM3 (developed by the IWA working groups). To be able to develop a method that may later on be used for online control, the full models are reduced based on the technique In Lukasse (1996). To ensure that the reduced models keep the same prediction capabilities as the full models, parameters of the reduced models are calculated based on the Least Squares principle, The formulated optimal control problem is solved based on the decompostion-coorcdination method that involves time decomposition in a two layer structure. MATLAB software [5 developed to solve the problems for parameter estimation. fun and reduced mode! simulation. and optimal control calculation for the considered different cases of plant structures and biological models. The obtained optimal 00 trajectories produced the effluent state trajectories within prescribed requirements. These DO trajectories may be implemented in different SCADA systems to be tracked as set points or desired trajectories by different types of controllers.

▼ Helicopter Unmanned Aerial Vehicles (UAVs) present a challenging control problem since their dynamics are nonlinear, underactuated and non-minimum phase. Although it is inherently an applied research field, due to the difficulty of building and maintaining an experimental platform relatively few experimental results exist in the literature. The approach followed in this thesis is to combine rigorous analysis with thorough experimental testing. This testing ensures validity of the designs. We present our experimental platform which is designed to be flexible so that it can accommodate nonlinear control research. Existing accounts of helicopter testbeds focus on hardware details. Since autopilot software design and development also requires a significant investment, we describe our implementation which has been released as open source for the benefit of the community. Due to the intractability of existing helicopter models, many control designs use non-physical inputs. We propose simple, invertible expressions relating the non-physical inputs to the physical inputs. In particular, modelling of the main rotor typically results in complicated expressions with extensive state dependence. While it is unlikely that angular velocity has a significant influence on the thrust, we show using experimental results that previous attempts to simplify this expression using a hover assumption are invalid during vertical flight. The platform is validated using a model-based PID control law. This control is derived using passivity to ignore nonlinear terms which do not affect stability. Among the class of vehicles with similar flight capabilities, helicopters possess a coupling between the rotational inputs and translational dynamics which is unique. This coupling is sometimes referred to as the Small Body Force (SBF) and is ignored in the literature for controller synthesis. We derive an experimentally-validated control design which accounts for the effect of the tail rotor in the SBF. In addition, we show why the contribution of the main rotor flapping in the SBF cannot be compensated using the same approach, and give a robustness analysis of their effect on the closed-loop. Finally, based on recent results we propose a control design which accounts for state constraints by enforcing bounds on translational velocity and roll-pitch travel.

▼ As a significant class of nonlinear systems, bilinear systems (BLS) are extensively developed in the past years. In addition to their advantages over linear systems which are often not adequate to represent accurately many control processes, the BLS are particularly appealing in modeling biological systems in which parametric controls are of fundamental importance. This dissertation is aimed at making a contribution to the theory of bilinear control systems via Lie algebraic methods, and the application of accomplished results in immunology. To this end, the input-output relationship of BLS is studied in terms of Volterra series expansion which provides a convenient tool in examining the BLS stability as well as controllability. Moreover, the Volterra series associated with a BLS is in general an infinite series, and thus in practice, it is important to know how many terms are required to prevent the truncation error from exceeding the maximum allowance. Criteria of acquiring prescribed accuracy in terms of finite Volterra series are derived for BLS with uniformly bounded input or with exponentially stable linear subsystems. The problem of inverse system design which is capable of identifying both the input function and the state variables based upon the output data, is also considered. The observer theory of constant linear systems is then extended into a special class of bilinear systems with input matrices of rank one. In view of the functional similarity between immune processes and parametric control systems, a mathematical model of humoral immune response is presented and analyzed. The structural aspects of this nonlinear immune model is examined with the aid of bilinear control theory. Approximate immune models which are amenable to the control-theoretic analysis via foregoingly developed techniques are proposed. Some computer simulations are performed to show that the form of model responses is reasonable by comparing with the experimental data. Advisors/Committee Members: Mohler, R. R. (advisor).

▼ Hallucinations are often considered a sign of psychotic illness, but are also common in other diagnostic groups and individuals without mental health problems. This thesis uses Perceptual Control Theory (PCT), a cybernetic model which explains behaviour and cognition in terms of control processes regulating ongoing perception according to internally represented goals, as a theoretical framework to understand hallucinations. First, a theoretical/conceptual paper (Paper 1) examines how PCT provides an integrated account of (i) the mechanisms responsible for the formation of hallucinations, (ii) their phenomenological heterogeneity, (iii) the interaction between these mechanisms and environmental factors that might contribute to the formation of hallucinations, and (iv) the processes leading to different affective reactions to hallucinatory experiences (e.g. distress). The main implications of this model are discussed in the context of pertinent theoretical and empirical literature, and relevant clinical and research implications are considered.Second, this thesis includes an empirical investigation (Paper 2) examining two PCT-informed hypotheses in a cross-section of 22 clinical and 18 non-clinical individuals with auditory verbal hallucinations (“hearing voices”), namely (i) that the content of voices will be thematically linked to the participants’ personal goals, and (ii) that affective reactions to voices will depend on the extent to which voices facilitate and/or interfere with important personal goals. The analysis revealed that 82.5% of participants reported voices that thematically matched at least one of their reported goals. As predicted, affective reactions to voices were strongly associated with measures of interference and facilitation of goals, even when controlling for important covariates (e.g. participants’ history of mental health difficulties; voices’ content, frequency and duration).Finally, a critical evaluation is provided (Paper 3), where the methodological strengths and limitations of the work presented in the present thesis are discussed with the aim to reflect on the research process, and inform future investigations into the topics considered in this thesis.

▼ Neurological damage often results in motor impairments and reductions in individualsâ€™ functional abilities, particularly when the upper limbs are affected. Many individuals fail to achieve potential recovery of hand function due to insufficient volume of arm-hand training. Robotic rehabilitation has been proposed as an adjunct to physical therapy to meet this shortfall. However, it may be the case that functional recovery is also limited by practice. It has been observed that advances in motor control theory, mostly arising from computational modelling of behavioural data, have not been integrated in rehabilitation practice. The relatively new field of rehabilitation robotics presents a perfect application and testbed for principles of motor theory. Moreover, one specific motor theory, perceptual control theory (Powers, 1973, 2008), has been identified as architecture for designing robotic control architectures (Young, 2018). In this thesis, we commence a research agenda that aims to test the proof-of-principle of PCT to inform robotic motor rehabilitation. The thesis consists of five original research reports. Two systematic reviews were conducted. The first aims to establish whether end-effector devices for arm and hand rehabilitation are efficacious in reducing impairment and improving functional outcomes. Findings suggested that device training may be efficacious for acute, subacute and chronic stroke patients. Thus it was determined that a research agenda which aimed to inform device development through motor theory was justified. A second systematic review evaluated the research literature regarding PCT models of manual tracking performance, in order to determine the extent to which PCT can account for motor performance in the task. Several key limitations in the PCT modelling literature were found. These limitations were investigated in a series of tracking experiments in which PCT models were optimised to, and simulated individual performance. In the first experiment, we developed a test for model individual-specificity. This was applied to PCT models and it was found that optimised PCT models simulated performance at validation (one-week later) with a higher degree of accuracy than a general PCT model. This demonstrates that the PCT model can discriminate between individual control characteristics. In the second experiment, we aimed to establish the effect of delay on model performance as it was not clear whether PCT models could compensate for long feedback delays that are present in the central nervous system. Four PCT model architectures were compared. The standard PCT position control model showed a reduction in model fit to anticipatory tracking behaviour at increasing delays. Conversely, models that controlled a novel perceptual variable (integrated motion representations) showed no such cost to performance at longer delays. Thus, given the appropriate controlled perceptual variable, PCT models can compensate for sensorimotor delays in motor performance. In the final experiment we aimed to… Advisors/Committee Members: TYSON, SARAH SF, WEIGHTMAN, ANDREW APH, Mansell, Warren, Tyson, Sarah, Weightman, Andrew.

▼ The span of control is the most discussed single concept in classical and modern management theory. In specifying conditions for organizational effectiveness, the span of control has generally been regarded as a critical factor. Existing research work has focused mainly on qualitative methods to analyze this concept, for example heuristic rules based on experiences and/or intuition. This research takes a quantitative approach to this problem and formulates it as a binary integer model, which is used as a tool to study the organizational design issue. This model considers a range of requirements affecting management and supervision of a given set of jobs in a company. These decision variables include allocation of jobs to workers, considering complexity and compatibility of each job with respect to workers, and the requirement of management for planning, execution, training, and control activities in a hierarchical organization. The objective of the model is minimal operations cost, which is the sum of supervision costs at each level of the hierarchy, and the costs of workers assigned to jobs. The model is intended for application in the make-to-order industries as a design tool. It could also be applied to make-to-stock companies as an evaluation tool, to assess the optimality of their current organizational structure. Extensive experiments were conducted to validate the model, to study its behavior, and to evaluate the impact of changing parameters with practical problems. This research proposes a meta-heuristic approach to solving large-size problems, based on the concept of greedy algorithms and the Meta-RaPS algorithm. The proposed heuristic was evaluated with two measures of performance: solution quality and computational speed. The quality is assessed by comparing the obtained objective function value to the one achieved by the optimal solution. The computational efficiency is assessed by comparing the computer time used by the proposed heuristic to the time taken by a commercial software system. Test results show the proposed heuristic procedure generates good solutions in a time-efficient manner. Advisors/Committee Members: Chin-Sheng Chen, Shih-Ming Lee, Ronald Giachetti, Irtishad Ahmad.

▼ This thesis considers optimization problems defined over a network of nodes, where each node knows only part of the objective functions. We are motivated by broad applications of these problems within engineering and sciences, where problems are characterized by either complex networks with a large number of nodes or massive amounts of data. Algorithms for solving these problems should be implemented in parallel between the nodes, and are based only on local computation and communication, necessitating the development of distributed algorithms. Our interest, therefore, is to study distributed methods for solving networked optimization problems, where our focus is on distributed gradient algorithms. In particular, we move beyond the existing results to significantly enhance the performance and reduce the complexity of distributed gradient methods, while taking practical issues, such as communication delays and resource uncertainty, into account. Our goal is to bridge the gap between theory and practice, leading to significant improvement in their performance for solving real-world problems. The remainder of this thesis is to focus on three main thrusts – first, we study the impact of communication delays, an inevitable issue in distributed systems, on the performance of distributed gradient algorithms. Our results address a notable omission in the existing literature, where the delays are often ignored. Second, we study different variants of distributed gradient algorithms, and show that under certain conditions we can improve their convergence. Finally, we study an important problem within engineering and computer science, namely, network resource allocation. For solving this problem, we propose distributed Lagrangian methods and show that our methods are robust to resource uncertainty. In addition, we design a novel algorithm, namely, the distributed gradient balancing protocol, for solving a special case of network resource allocation problems. We show that our algorithm achieves a quadratic convergence time, which improves the convergence of the existing algorithms by a factor of n, the size of the network.

▼ Neurological damage often results in motor impairments and reductions in individuals' functional abilities, particularly when the upper limbs are affected. Many individuals fail to achieve potential recovery of hand function due to insufficient volume of arm-hand training. Robotic rehabilitation has been proposed as an adjunct to physical therapy to meet this shortfall. However, it may be the case that functional recovery is also limited by practice. It has been observed that advances in motor control theory, mostly arising from computational modelling of behavioural data, have not been integrated in rehabilitation practice. The relatively new field of rehabilitation robotics presents a perfect application and testbed for principles of motor theory. Moreover, one specific motor theory, perceptual control theory (Powers, 1973, 2008), has been identified as architecture for designing robotic control architectures (Young, 2018). In this thesis, we commence a research agenda that aims to test the proof-of-principle of PCT to inform robotic motor rehabilitation. The thesis consists of five original research reports. Two systematic reviews were conducted. The first aims to establish whether end-effector devices for arm and hand rehabilitation are efficacious in reducing impairment and improving functional outcomes. Findings suggested that device training may be efficacious for acute, subacute and chronic stroke patients. Thus it was determined that a research agenda which aimed to inform device development through motor theory was justified. A second systematic review evaluated the research literature regarding PCT models of manual tracking performance, in order to determine the extent to which PCT can account for motor performance in the task. Several key limitations in the PCT modelling literature were found. These limitations were investigated in a series of tracking experiments in which PCT models were optimised to, and simulated individual performance. In the first experiment, we developed a test for model individual-specificity. This was applied to PCT models and it was found that optimised PCT models simulated performance at validation (one-week later) with a higher degree of accuracy than a general PCT model. This demonstrates that the PCT model can discriminate between individual control characteristics. In the second experiment, we aimed to establish the effect of delay on model performance as it was not clear whether PCT models could compensate for long feedback delays that are present in the central nervous system. Four PCT model architectures were compared. The standard PCT position control model showed a reduction in model fit to anticipatory tracking behaviour at increasing delays. Conversely, models that controlled a novel perceptual variable (integrated motion representations) showed no such cost to performance at longer delays. Thus, given the appropriate controlled perceptual variable, PCT models can compensate for sensorimotor delays in motor performance. In the final experiment we aimed to investigate…
