| DESCRIPTION | The study-unit presents methodologies and tools for the modelling, analysis and control of continuous-time linear dynamic systems. Both classical transfer function and modern state-space approaches are considered. After a brief introduction to control systems engineering, the unit covers: transfer function and state-space models of physical dynamic systems; a set of theoretical concepts and tools to study and analyse the stability and behaviour of control systems, in both time and frequency domains; and the theory, design, and implementation of lead-lag compensators, PID controllers, and state-space regulators, trackers and observers. Study-Unit Aims: The aims of this study-unit are to: - introduce the field of Automatic Control Systems via a number of real-life applications; - present techniques for obtaining transfer function and state-space models of physical dynamic systems composed of electrical, mechanical, thermal and hydraulic components; - present theoretical tools for the analysis of linear open and closed-loop continuous-time systems, in both the time and frequency domains. These include: state-space analysis, transient response, steady-state errors, root-locus analysis, Bode and Nyquist plots, Routh's and Nyquist stability criteria, stability margins, and other related concepts; - present the theory, design and implementation of a number of control methods for linear continuous-time systems. These include: lead-lag compensation, PID control, state-feedback control with state-observers. Learning Outcomes: 1. Knowledge & Understanding By the end of the study-unit the student will be able to: - describe fundamental concepts and terminology related to Control Systems; - obtain transfer function and state-space models for continuous-time, linear time invariant systems; - apply appropriate tools to analyse the behaviour/performance of continuous-time linear open and closed-loop dynamic systems in the time and frequency domains; - select an appropriate control design methodology to address a given problem. 2. Skills By the end of the study-unit the student will be able to: - apply the presented theoretical concepts and tools to solve problems related to continuous-time feedback systems; - design closed-loop control laws (lead-lag, PID and state-feedback) for linear time invariant continuous-time systems, to meet some given performance specifications; - simulate and evaluate the behaviour of linear control systems using Matlab/Simulink; - implement the designed control systems physically, using analogue electronic circuitry and Matlab/Simulink-based real-time computational hardware; - test, evaluate and fine-tune the designed automatic control systems.
