A Novel fuzzy Control Strategy for Maximum Power Point Tracking of Wind Energy Conversion System

This paper presents a novel fuzzy control strategy for maximum power tracking of Wind Energy Conversion System (WECS) using a Permanent Magnet Synchronous Generator (PMSG) supplying a DC load through a AC/DC converter. The proposed fuzzy controller allows to extract the maximum power from the wind turbine which leads to an optimal operation of the WECS. First, the dynamics behaviour of the (WECS) is represented by a Takagi Sugeno (T-S) fuzzy model. Then, a reference model-based tracking controller is proposed to achieve a maximum power point tracking even when we consider varying wind speed profile. The controller gains are calculated by solving Linear Matrix Inequalities (LMIs). Finally, simulation results are presented to illustrate the effectiveness of the proposed approach.
