An Analysis Comparing the Performance of Wind Energy Conversion Systems Utilising FLC Controllers

Abstract

This research gives a comparative analysis of Proportional-Integral (PI) and Fuzzy Logic Control (FLC) controllers for control systems of wind energy conversion systems (WECS). The PI controller is a conventional control technique that is extensively employed due to its simplicity and efficacy in regulating system behaviour through the adjustment of proportional and integral gains. FLC, on the other hand, utilises language rules and fuzzy logic reasoning to imitate human decision-making processes, providing a flexible and adaptable control strategy. The selection between PI and fuzzy controllers is dependent on the particular demands and limitations of the control application. The comparison study evaluates the performance of PI and Fuzzy controllers in various control scenarios, specifically in the scenario of speed control of cascaded doubly fed induction generator (CDFIG). Wind energy conversion systems consist of CDFIG connected to the grid via a matrix converter or rectifier and inverter. This study will present numerical simulation results conducted using the MATLAB/Simulink program to demonstrate the feasibility and efficacy of the proposed control technique
