| DESCRIPTION | • Introduction to Control Systems Engineering - Open and closed loop systems: Example of practical automatic control systems. Concept of system order, stability, response, accuracy. • Linear Systems Modelling - Block diagram representation of systems in s-domain, open and closed-loop relationships, unity feedback. Signal flow diagram representation of systems. Modelling of linear system elements: electrical, mechanical, electro-mechanical, thermal, fluid, electro-mechanical analogy • Linear Control Systems Analysis - Time domain response of 1st and 2nd order systems: System response dependence on poles, damping, natural/damped frequency of oscillations, response to a step input. - The servomechanism as a practical control system: Position control, speed control, derivative feedback and introduction to concepts of integral and PID control. Study-unit Aims: This study-unit introduces the basic concepts systems modelling and of automatic control systems covering the analysis of linear time-invariant feedback control systems via classical control theory. Learning Outcomes: 1. Knowledge & Understanding: By the end of the study-unit the student will be able to: - explain the advantages of closed loop over open loop systems - compare the behaviours of first order and higher order systems - explain the oscillatory, stable or unstable behaviour of physical systems though the use of Laplace modelling and classical control theory. 2. Skills: By the end of the study-unit the student will be able to, given a physical linear dynamic system: - derive the correct transfer function model describing its behaviour in s-domain - represent the system as both a block diagram and a signal flow graph - predict the system's time domain behaviour to various inputs Main Text/s and any supplementary readings: (availability at the Library or otherwise is indicated against each entry) - Kuo B.C., 1995.
