中文摘要 |
研究了一种线性不确定系统的鲁棒容错控制问题. 针对执行机构和敏感器故障, 运用线性矩阵不等式(LMI)方法, 提出一种对执行机构和传感器失效具有完整性, 且满足给定控制指标的输出反馈H∞鲁棒容错控制设计方法. 将该方法应用于卫星姿态控制系统的容错控制并进行了数学仿真, 仿真结果验证了方法的有效性. |
英文摘要 |
The robust fault-tolerant H-infinity control problem of uncertain linear system is studied in this paper. The solution of this problem is obtained for a H-infinity output feedack controller by a linear matrix inequality (LMI) approach. The simulation of a satellite attitude control system with actuator and sensor faults validates that this solution is effective and more suitable in on-board real-time computation. |
