The partial loss of reaction wheel effectiveness is tolerated, and reaction wheel misalignment is also compensated. The Lyapunov stability analysis shows that the closed- loop attitude system is guaranteed to be almost asymptotically stable in 铿乶ite-time. An illustrative example of a satellite is given, and simulation results show the effectiveness of the derived control law.
