N2 - The paper investigate the fault-tolerant attitude control for the rigid spacecraft attitude system with external disturbances and actuator faults simultaneously. Firstly, an iterative learning-based observer is proposed, which can estimate the actuator faults with high precise even in presence of the disturbance. Then, employing the estimate informations of the designed observer, a sliding-mode fault-tolerant control scheme is designed to guarantee stability of the closed-loop system and reject to the external disturbance. Finally, the simulation results are given to validate the effectiveness of the proposed approaches.
