Highlights An adaptive fault-tolerant control framework for spacecraft formation flying is proposed. A special function is introduced to guarantee the prescribed performance. A nonsingular fast terminal sliding mode control scheme is adopted to account for external disturbances and uncertainties.
Abstract This paper investigates an adaptive fault-tolerant control problem for spacecraft formation flying (SFF) with actuator faults, external disturbances, and unknown inertial uncertainties. First, fault factors are introduced to describe the SFF orbit model with consideration of actuator bias faults and loss of actuator effectiveness. Then, an adaptive fault-tolerant controller is proposed by incorporating prescribed performance function, improved terminal sliding mode control and the proposed adaptive law. Finally, rigorous theoretical analysis ensures the uniformly ultimately bounded stability of the system through Lyapunov theory and simulation verifies the proposed algorithm.
