Hybrid Control Based on Sliding Mode Fuzzy of DFIG Power Associated WECS

In this paper, the robust algorithm based on the coupling of sliding mode control and the fuzzy logic control is concerned to ameliorate the robustness and the performances of a variable speed wind energy conversion system (WECS) based on vertical axis wind turbine (H-darrieus) with direct attack, connected to electric power grid with a doubly fed induction generator (DFIG). The control independently of stator active and reactive powers is used by stator flux orientation strategy. The active power reference derived from turbine's mechanical power. The hybrid fuzzy sliding mode control permits to enjoy the advantages of these two techniques in order to reduce the chattering phenomenon. The proposed approach is analysed and compared between SMO and SMOF by Simulink/Matlab environment. The simulation results show good performances and robustness of SMOF.
