Maximum power point tracking of a wind generation system based on T-S fuzzy model

Abstract

The current paper is presenting a Takagi-Sugeno (T-S) fuzzy controller designed for a wind generation system in the objective of Maximum Power Point Tracking (MPPT). The considered Wind Energy Conversion System (WECS) is composed of a wind turbine and a Permanent Magnet Synchronous Generator (PMSG) associated to an AC-DC converter. First, the WECS fuzzy model is presented based on T-S approach. Next, the proposed controller is designed using Linear Matrix Inequalities (LMI) techniques and Lyapunov stability approach. Simulation results bring out the efficiency of the proposed scheme.
