Credit points: 7.1
Coordinator: Prof. M. C. Good
Prerequisite: 436-206 Electro-Mechanical Machine Behaviours, Level 2 Mathematics and 436-205 Computational Mechanics and Computer Programming
Contact: 26 hours of lectures, 13 hours of tutorials and laboratory work
Timetable: First semester
Objectives:
On completion of this subject students should be able to:
- formulate linearised mathematical models of mechanical engineering systems
- determine time - and frequency - domain responses of such systems
- analyse quantitatively the effects of feedback on system performance
- make effective use of computational aids of the analysis and design of continuous control systems
- design simple linear, continuous feedback-controllers
- simulate system performance including the effects of simple nonlinearities
Content:
Analysis: Review of mathematical representations of linear continuous dynamical systems; Fourier and Laplace analysis of signals and systems. Linearisation of models. Transient and steady-state time responses, frequency response, stability. Root locus, Bode and Nyquist plots. Effects of feedback on steady-state accuracy, sensitivity, disturbance rejection, speed and stability of response.Design: Classical compensator design using root locus and frequency response techniques; lead, lag, lag-lead, PID, Cascade and feedback compensation.
Nonlinearities: Effects of simple nonlinearities on control system performance; Coulomb friction, saturation, backlash; sinusoidal describing functions, limit cycles. Simulation of nonlinear systems using Matlab.
Case studies: Detailed examination of control design issues for representative mechanical and manufacturing engineering systems, such as machine tool axis or active vehicle suspension.
Assessment:
A two-hour examination; tests, assignments and laboratory reports, not exceeding 20 pages.
