The aim of this paper is the hybrid fuzzy sliding mode control of a doubly fed induction generator (DFIG) in a wind turbine. This type of control is introduced to avoid the major disadvantage of variable structures systems which is the chattering phenomenon. Using the variable structure is to ensure the high dynamic of convergence and the robustness towards parametric variations and disturbances. Whereas the fuzzy control is introduced here in order to remove residual vibrations in high frequencies. We have used that approach to control the active and reactive powers exchanged between the stator circuit and the grid. Those variables are decoupled by using the vector control technique.
