DESCRIPTION - summary of the module content

The advancement of technology during the 20th century put control engineering on the map - and it still plays a critical role in everything from simple household washing machines to high performance fighter aircraft. This module will give you a fundamental understanding of control engineering for single input single output systems. In particular, you will analyse the fundamental concept of feedback and its impact on system dynamics. You will study the performance of closed loop systems from a time domain and frequency domain perspective. Classical approaches to studying closed loop systems will be introduced including root-locus, Nyquist and Bode diagram methods. The module will also describe a method for parameterizing all stabilizing controllers for a given plant model, and how this result can be used from a design perspective. The module will also introduce the fundamentals of proportional-integral-derivative (PID) control, which you will use to analyse and design control systems. The module will describe the concepts of gain and phase margins and the H-infinity norm, for assessing the robustness of closed loop systems to modelling uncertainty. The lectures are supported by computer laboratories for modelling and simulation of systems using the Control Engineering toolbox in Matlab.

AIMS - intentions of the module

This module introduces the concepts of feedback and stability for single input single output systems. It exposes you to standard control concepts and calculations in both the time and frequency domain. The module will introduce the concepts of gain and phase margins and the H-infinity norm, for assessing the robustness of closed loop systems to modelling uncertainty. A detailed analysis of proportional, integral and derivative controllers for single input single output control loops will be explored. The aim is to present several analytical, numerical and graphical techniques to analyse and design control systems for single input single output systems. It also provides an introduction to the Control Engineering toolbox in Matlab for use as a design tool to realise and evaluate the performance of control systems.
