Abstract
A new adaptive second-order sliding mode control method is proposed for the attitude control of flexible spacecraft during slew maneuver. Compared with traditional sliding mode control, the second sliding mode control approach guarantees the same robustness and precision, feature higher order accuracy and can be exploited to eliminate the chattering phenomenon. In the present paper, a second-order sliding mode controller is designed by treating the input of the system as a new state variable, while using it's derivate as the actual control. A fuzzy-neural network is adopted to approximate the strong coupling uncertain nonlinear dynamics, and the on-line adaptive weights tuning law is derived, the global stability of the system is guaranteed. Simulation results show the effectiveness of the proposed method.
