  Aiming at the improvement of operation reliability, the study present a sensor fault diagnosis method for the doubly-fed wind generator control system. Firstly, a double-fed wind generator modeling method on consideration of unknown input disturbance is presented. The designs of Luenberger observer and sliding mode observer are following. The former is in order to change the nonlinear system into a linear time-invariant one and the latter for the elimination of the influence of unknown input disturbance in fault diagnosis. Finally, an observers-based sensor fault diagnosis method is proposed and its effectiveness is verified through experiments with different types of sensor faults.
