The aim of this module is to establish for the students a fundamental
approach to the design of linear control systems.
Control system design (11L)
- System dynamics, stability
and instability, principles and use of root locus plots, derivation of
Nyquist stability criterion, Bode theorems and plots.
- Design of simple P.I.D.
controllers and phase compensators. Sensitivity, complementary sensitivity
and SISO robustness. Non-minimum phase systems and limitations, bandwidth.
Delays in systems.
- Two degree of freedom
Introduction to Coursework (1L)
- Case studies and simulation.
Case studies and design by simulation and computer software, e.g. use of
Matlab. Four hours DPO time plus report (further four hours).
On completion of the module students should:
- Understand the role and
importance of feedback for the control of uncertain dynamical systems;
- Be able to demonstrate the
information conveyed via root locus diagrams for transient behaviour and
basic frequency response analysis using Nyquist (polar) and Bode plots;
- Be able, following its
basic derivation, to illustrate the use of the Nyquist stability criterion
with both open loop stable and open loop unstable systems;
- Understand factors which
limit achievable performance in feedback systems;
- Be able to use analytical
tools to understand trade-offs (e.g. Bode gain/phase relations,
- Be able to translate
general requirements for robustness and performance into specifications on
the open-loop frequency response;
- Be able to use computer
software for simple control system design and system simulation;
- Be able to design simple
compensators to achieve such specifications.
