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, Bode and Nyquist 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
Nyquist Diagrams: construction, calibration, Nyquist stability criterion
Compensator Design Using Bode Diagrams: Lag and Lead compensator design
Laboratory: control of electrical machines
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:
