Abstract

An extremely flexible design method for developing optimal fixed structure controllers is to place the cost of subsystem interconnections in the cost function. The optimal gain is then obtained via a numerical search procedure. Previous work with this class of cost functions has only made use of steepest-descent searches. In this paper, a descent function search algorithm is presented that significantly decreases the number of iterations needed to converge. An example shows that the descent function algorithm has superior convergence properties
