This paper presents new scheme for the Active Fault Tolerant Control (AFTC) for Wind Energy Conversion Systems (WECS) subject to sensors faults. The scheme uses multiple sensors- observer and a switching mechanism to automatically detect, isolate and accommodate the sensor faults. "Takagi-Sugeno" (TS) is employed to represent a nonlinear WECS. By using Linear Matrix Inequality (LMI) formulation, the TS fuzzy model of WECS is used to design output feedback observer-based controllers. The control scheme is tested for WECS and provides satisfactory results
