中文摘要：
研究了一类卫星姿态控制系统的鲁棒容错控制问题。针对执行机构性能下降或者出现故障，提出了一种圆盘极点指标约束下，对执行机构故障具有完整性且满足H∞扰动衰减指标的状态反馈鲁棒容错控制设计方法。分析了圆盘极点指标与H∞指标的相客性，并在相容指标约束下，给出了鲁棒H∞容错控制器存在的充分条件。同时将该方法应用于卫星姿态控制系统的容错控刺并进行了数字仿真，仿真结果验证了方法的有效性。
英文摘要：
The robust fault-tolerant control problem of satellite attitude control systems is studied in this paper. Considering the actuator faults, the solution of this problem is obtained to meet the requirements of H-infinity state-feedback controller with circular disk pole constraints. Furthermore, the consistency theory on circular disk pole index and H-infinity index is setup, and sufficient conditions for the existence of robust H-infinity fault-tolerant controller are given. A simulation of applying in a satellite attitude control system with actuator faults shows the validity of the proposed method.
