Sliding mode control of a wind turbine with exponential reaching law

Abstract

This paper presents a novel control strategy of a wind turbine based on Doubly Fed Induction Generator (DFIG) to maximize the electrical power generated by the DFIG, for low wind speed. To achieve this objective, the nonlinear sliding mode control with exponential reaching law (ERL), the Bees algorithm and the fuzzy maximum power point tracking MPPT are applied to the system. The ERL and the Bees algorithm are used to obtain a good reference tracking and to suppress the chatter phenomenon. The effectiveness of this control strategy is proven through the simulation results.
