For the momentum wheel control system of satellite, a method to design sliding mode observers for reconstructing actuator fault is presented. It uses the equivalent output injection concept to explicitly reconstruct fault signals, and uses concept to design the sliding motion so that the effect of the uncertainty on the reconstruction of the faults will be minimized. This method can estimate the existing fault and detect faults generating in momentum wheel control system of satellite. The effectiveness is proved by simulation results.
