Overview
The course introduces basic concepts of feedback control systems using a number of practical examples. Mathematical modelling of physical systems and representing them in block diagrams with transfer functions are presented. Basic control system response characteristics (stability, transient response, steady state response) and analysis and design procedures are introduced using first and second order systems. Absolute and relative stability, the Routh-Hurwitz criterion and the root locus diagram are developed as general analysis and design tools. PID controllers and improvement of system performance using compensation techniques are investigated. The frequency domain approach is developed through use of the Bode diagram and application of lead and lag compensators.
At the end of the course students will be able design a controller for any simple physical system in order to accomplish the specifications for the controlled parameter (eg temperature, pressure, weight, level, position). This will include mathematical modelling of the physical system, selection and design of an appropriate controller, validation of the overall system performance.
The laboratory exercise develops the use of MATLAB/SIMULINK as computer-based tools. Effects of modelling approximations and the response characteristics are investigated.
