Summary:This research presents an observer-based adaptive fault-tolerant control for wind turbine systems subject to the pitch angle sensor fault. The design mechanism is based on integrating a robust fuzzy observer with a backstepping-based adaptive control approach. The Lyapunov concept is adopted to derive the uniformly ultimate boundedness stability of the overall system by taking into account the fuzzy approximation error. Therefore, the generator speed as a control objective is appropriately regulated. Different simulation scenarios verify the ability of the proposed control algorithm applied to a wind turbine system against the external disturbance, the fuzzy approximation error, the parametric uncertainties and the sensor fault.
