The reaction flywheel is one of the most common actuators in the satellite attitude control, which has a significant impact on satellite attitude. Based on the observer, a finite time control system is designed to resolve the fast stabilization control problem of the spacecraft with the reaction flywheel failure and the unknown disturbance. Using the sliding mode technology, a finite time fault tolerance control law is proposed. Considering the unknown parameters of the actuator effectiveness of the spacecraft and the external disturbance, an observer estimating the interference is designed to improve the disturbance rejection. Finally, the convergence of the designed control system is verified using the Lyapunov function. The results demonstrate the proposed controller has good robustness to the actuator effectiveness and the unknown disturbance.
