<![CDATA[This study proposes a fuzzy sliding mode control strategy to realize wind energy conversion optimization based on doubly-fed induction generator (DFIG). Its operational points in partial load zone can be electronically controlled. Chattering in wind energy conversion sliding mode control system is greatly alleviated based on fuzzy switching gain adjustment. The purposes including the maximum power point tracking, decoupling control of active and reactive power of fed induction generation system are fulfilled. Fitful and random wind speeds are mathematical modeled. Simulation results verified effectiveness and feasibility of the proposed control strategy under the two types of wind speed and indicate that the whole control system has better robustness against uncertainties and can guarantee the power quality.]]>
