To solve the rigid spacecraft attitude maneuver problem, an adaptive fuzzy fault-tolerant sliding mode controller is designed. The controller is based on the terminal sliding mode scheme. The adaptive learning algorithm and the fuzzy logic system are designed to estimate the attitude tracking dynamics. The stability of the controller is proved by Lyapunov method. Finite-time convergence of spacecraft attitude orientation to the neighborhood of the equilibrium point is obtained. Finally, a numerical simulation is employed to illustrate the advantages of the proposed controller. Simulation results confirm that the designed controller yields high control precision and great fault-tolerant capability.
