Description including Unit Aims

In this unit, the concepts of classical control theory are introduced. These are applied to the analysis and design of control systems, with particular emphasis on root locus and Bode techniques. Lectures are supported by laboratory work on stability analysis and position control.

  • Elements: Introduction & overview
  • System Models: time domain models, time response, forced and natural response, transfer functions
  • Control Systems Representation: block diagrams, signal flow graphs, Mason’s rule
  • Open and Closed-Loop Systems: sensitivity, transient response, steady-state error, disturbances
  • Introduction to Control Systems Design: pole position, 2nd order system response, standard performance measures, additional poles and zeros.
  • System Stability: Routh-Hurwitz stability criterion
  • Steady State Errors: system type number, error constants
  • Root Locus: introduction, root locus criteria, construction method, interpretation, compensator (PI, Lag, PD and Lead) design using root locus
  • Frequency Response Techniques: frequency response from pole-zero diagram, Bode diagrams, system identification, the pure delay, gain and phase margin
  • Compensator Design Using Bode Diagrams: Lag and Lead compensator design
  • Laboratory: control of electrical machines

Intended Learning Outcomes

Students will have a foundation in classical control theory and will be able to analyse and specify system performance parameters. This will include an understanding of the relative merits and implementation of various design methodologies in order to design control schemes to meet a particular specification.

Having completed this unit, students will be able to:

  1. Analyse and specify system performance parameters for classical control systems
  2. Evaluate the relative merits of various design methodologies to meet a particular specification
