Many non-linear controllers have been used to improve system performances and robustness of double fed induction machine (DFIG) based wind turbines like sliding mode control (SMC). However, this type of controller is less efficient due to a sign function that can lead to chattering phenomenon. To overcome this deficiency, the function is replaced by fuzzy logic control (FLC). This is what is proposed in this paper which deals with doubly fed induction generator (DFIG) based wind turbine conversion system (WECs) by sliding mode control and fuzzy sliding mode control (FSMC). The system control have been applied to the back to back converters that connect rotor windings to the grid, For the rotor side converter (RsC), we have presented sliding mode control, and fuzzy sliding mode control to monitor active and reactive powers independently, when the grid side converter (GsC) was set to keep a constant DC voltage with a desired power factor. The effectiveness of the proposed control systems is tested using Matlab/Simulink software under a wind speed fluctuation and parameters variation. The simulation results showed that the FSMC is more robust and has better dynamic performances than the SMC control
