Abstract

A set of standard evolution strategies is implemented in order to find the optimal tuning of a structured controller. The structured controller design problem is a non-convex optimization problem. The usual solution technique involves the use of branch and bound global search algorithm. Standard evolution strategies are able to find the global optimum with comparable solution quality, less overhead and considerable gain in computation time.
