Behaviour of linear continuous-time control systems

Module overview. Before a control system is designed it is necessary to specify what is expected for the closed-loop control behaviour. The dynamical behaviour and its static properties must be described. The basic requirements for control system design are given. These are precisely defined for the case of disturbance and command behaviour and illustrated by examples. Performance indices to measure the quality of the control system in the time domain using standard quantities are introduced, e.g. maximum overshoot, rise time and settling time. Integral performance indices and their determination in the domain for the case of quadratic forms are also given.

Module objectives. When you have completed this module you should be able to:

  1. Know the basic requirements of control system design.
  2. Determine static and dynamic properties.
  3. Judge and measure the performance of control systems in the time domain.


Module prerequisites. Transfer function, Laplace transform.
