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
