A method for the effective design of controllers in the frequency domain
Abstract
This paper is concerned with the design of single-input single-output controllers in the frequency domain. The classical frequency domain design technique is a trial-and-error method based on graphical information on the plant's dynamical behaviour. In contrast, the method described here is based on numerical optimization of the controller's parameters in order to obtain the desired behaviour of the closed-loop system. The key idea is a reformulation of the design problem as an approximation problem which can then be solved numerically.
