Abstract

Based on fuzzy control technique, the fault-tolerant sliding mode control problem is investigated for near space vehicle (NSV) attitude dynamics in this paper. Firstly, the nonlinear dynamics of NSV is given. Then, T-S fuzzy model for NSV with additive actuator fault is established. The fuzzy sliding surfaces for NSV is designed by using a Lyapunov function, and the fuzzy fault-tolerant sliding mode control law is proposed such that the NSV with actuator fault confined on the sliding surfaces is asymptotically stable. Finally, simulation result is given to illustrate the feasibility of the proposed technique.
