考虑输入饱和的近空间飞行器姿态容错控制
Fault-tolerant attitude control for near space vehicles with input saturation
摘要
Abstract
In this paper, a robust fault-tolerant attitude control scheme is investigated for the near space vehicles (NSVs) with actuator faults, input saturation and unknown external disturbances. Firstly, a super-twisting second order sliding mode disturbance observer is developed to estimate the unknown compound disturbances including system uncertainties, external disturbances and actuator faults. Then, based on the backstepping technology and an auxiliary system constructed to solve the input saturation problem, a attitude fault-tolerant controller is proposed. In addition, the convergence of all the closed-loop system signals under the designed controller is rigorously proved using Lyapunov method. Finally, the proposed control scheme is applied to the attitude control of the NSV, and the effectiveness of this proposed control scheme is demonstrated by the simulation results.关键词
