Adaptive Fuzzy Fault-Tolerant Control of Flexible Spacecraft with Rotating Appendages

Abstract This paper focuses on the attitude control problems of spacecraft with external interference and platform actuator failure. The Lagrange method is used to establish dynamic models complex composed rotating appendages platform, quaternion describe kinematics. Second, a fault-tolerant algorithm that combined adaptive fuzzy finite time sliding mode proposed for fixed-time schemes are parts achieve stable rotation components relative platform. Finally, numerical simulation performed verify superiority effectiveness laws, comparisons other methods presented.
