In this paper, the problem of spacecraft attitude control with soft faults of actuators is investigated. A robust fault-tolerant controller is proposed in spacecraft with the explicit model predictive control. Firstly, Fault model of the actuator is established with the method based on explicit model prediction. Then, considering the model uncertainty and the system state disturbance, the control problem based on the spacecraft actuator failure state was transformed into the multi-parametric quadratic programs (MPQP) under the constraints. Finally, a recursive process of combining and replacing solutions is given to extract the required explicit control laws. By designing the terminal cost function and constraint set appropriately, it is proved that the MPC controller is robust to the constraints applied in the closed loop of the uncertain system and the input to the stability of the origin state.
