| Aim: This course introduces students to the theory and practice of control system engineering. The course emphasizes the practical application of the subject to the analysis and design of feedback control. By introducing fundamental classical linear control theory combining with practical examples, students have opportunity to practise analysis and design of feedback control system including systems modelling, transient response analysis, performance specification, stability analysis and compensator design. |
Contents: The first step in the analysis of a dynamical system is to derive its mathematical model. Through several examples, the principles and procedures of system modelling are introduced. Especial attention to mechanical systems is paid. Transfer function and block diagramare introduced. Non-linear systems are linerazed in order to apply the linear control theory to non-linear systems.
The system analysis topics covered include: - transient response analysis - steady-state error analysis - roots-locus analysis - frequency response analysis.
The system stability can be examined by using the following methods: - routh's stability criterion - root-locus - Nyquist stability criterion
The characteristics of a control system are specified by using - delay time, rise time, peak time, overshoot and setting time in time-domain - phase margin, gain margin, and bandwidth in frequency domain.
The purpose of control engineering is to manipulate a system to fulfil some performance specifications determined by the design. If the system can not satisfy the specification by just adjusting parameter settings or by changes the system configuration, t is necessary to insert a compensator into the system. The commonly used compensators including PID, lag, lead, lead and lag compensators are introduced.
