摘要 基于滑模控制理论提出一种刚体卫星姿态稳定控制方法,实现对反作用飞轮部分失效故障的容错控制,以及对其安装偏差的补偿控制,并从理论上证明了所设计的控制器在有限时间内能够实现对闭环姿态控制系统的几乎全局渐近稳定控制.最后将所设计的控制器应用于某型卫星姿态稳定任务,仿真结果验证了所提出方法的有效性. An attitude stabilization scheme is presented for a rigid satellite. 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 finite-time. An illustrative example of a satellite is given, and simulation results show the effectiveness of the derived control law.
