Module Overview

EE2.lsa (Advised)

Module Aims

To introduce the principles of classical control analysis and design and the modern topics of state-space and sampled-data systems analysis.

Learning Outcomes
Upon successful completion of this module students will be able to:
  • model physical systems in the time and complex frequency domains,
  • use mathematical tools such as laplace and Z transforms and manipulate difference and differential equations, transfer functions and block diagrams to analyse and design simple single input/output control systems,.
  • understand the concept of pole-zero s-plane diagrams and apply root-locus techniques to design,
  • assess stability using Routh’s and Nyquist’s criteria and use root-locus sketching, polar and Bode plots to stabilise systems,
  • understand how systems are specified in terms of time and frequency and other performance criteria,
  • analyse and design compensators using root-locus, Bode plots and Nichols charts,
  • analyse systems using state-space representation,
  • assess stability, sampled-time response and steady-state errors for sample-data systems and apply to simple design examples.
