Computer-aided design of P or PI plus rate feedback compensators for linear systems

A computer-aided solution for the gains of P or PI plus rate feedback compensators based on an exact model-matching criterion is developed. The corresponding Matlab functions are developed, and the software listings are given. Using the developed design tool, control engineers are able to obtain P or PI plus rate feedback gains much more quickly than traditional methods of design. Demonstration example problems for control of linear plants are presented, and results are compared with those obtained by other approaches reported in the open literature.

► A closed-form solution to the P or PI plus rate feedback compensator design problem is obtainable by minimizing a mean-square error criterion. ► The design process is much less complicated and faster than other available graphical techniques. ► The design equations and the associated software may be used to evaluate designs obtained by classical techniques.
