Robust control design for wind energy conversion system using Genetic Algorithm (GA) tuned Fractional order controller

Abstract

Robust control technique is more important to achieve a regulated constant output voltage in wind energy conversion (WEC) system. This paper presents a robust controller design for WEC system using Genetic Algorithm (GA) tuned Fractional Order Controller (FOC). The main contribution in this paper is the design of Fractional order PI controller using Genetic algorithm, implementation using MATLAB/ SIMULINK and performance comparisons. Here the performance of Fractional Order PI Controller is compared with PI controller. The regulation of system with control approach under variable wind speed conditions such as fluctuation wind phenomena was also considered for performance comparison.
