摘要：

This paper proposed a robust fault detection approach using observer method. The developed observer is sensitive to faults in the state equation and output equation, whilst robust to the system disturbance. The multivariable dynamics of the wind turbine system are studied and a state space model is developed. The developed fault detection approach is applied to the wind turbine system with several actuator faults, component faults and sensor faults simulated. The simulation results showed the effectiveness of the proposed approach with the fault detection residual sensitive to all the faults while robust to the disturbance.
