A computer-aided method for digital controller design via optimization (Q805539)

A computational algorithm for the design of digital controllers is presented in this paper. The design procedure adopted here is based on matching frequency response of open-loop system with a reference model. The controller parameters are obtained by formulating the design problem as unconstrained optimization problem. The performance of the proposed method is illustrated by two examples. The reviewer points out, however, that the exact model matching method will yield exact matching of the closed loop system with the given reference model instead of an approximated result obtained by the method developed in this paper.
