Fuzzy-Sliding Mode Control Second Order of Wind Turbine Based on DFIG

This paper study a robust fuzzy sliding mode second order control for a horizontal axis wind turbine with DFIG (doubly fed induction generator) supplied directly in stator by grid and supplied by two converters side rotor (CSR) and grid (CSG) in rotor. In the first section, we present the model of the wind turbine system (mechanical and electrical part). In second part, in order to control the stator powers (active and reactive) of the DFIG, the robust control is proposed uses the combination between sliding mode second order strategy based on super twisting algorithm with fuzzy logic control is applied in order to reduce the chattering phenomenon and ameliorate the quality of energy on a classical sliding mode second order control. This technique (FSMSO) provides better performance and robustness (reduce the chattering effect, ameliorate the quality of energy). The simulation results of the whole system are introduced and discussed.
