Variable Structure Load Frequency Controller: Optimal Design and Chattering Reduction using Particle Swarm Optimization Algorithm

Abstract

This paper presents an optimal design of Variable Structure Load Frequency Controller using Particle Swarm Optimization Algorithm. The optimal design provides a simple systematic way for obtaining optimum feedback gains and switching vector for VSC. It also includes a new method to reduce the chattering associated with the Variable Structure Controllers (VSC). The proposed method has been applied to a single nonreheat area. Comparison with the literature shows the effectiveness of the proposed design approach.
