Evolutionary approach for automatic design of PID controllers

Abstract

In this paper a new approach for automatic design of PID controllers is presented. It is based on meta-heuristic hybrid algorithm which is a combination of the genetic algorithm and the imperialist one. Main characteristic of the proposed approach is capability to design the structure and the structure parameters of a controller. It is a big advantage because it eliminates trial and error process of design the controller structure. Moreover, the proposed approach has been developed in a way that allows to obtain controllers taking different control criteria and a different control object into consideration.
