Abstract

Controllers are widely used in power industrial field to control system because wide range of the tuned parameter. There are several methods which are used to tune the controller parameters. They are categorized into two types known as classical methods and modern methods. This paper presents the design of controller to tuned by the one of the modern algorithm techniques i.e. Particle Swarm Optimization (PSO). In this paper the use of PSO method tuned the PID parameter to make them more general and to achieve the steady state error limit, also to improve the dynamic behavior of the system. The performance and design criteria of automatic selection of controller constants are discussed below.
