| 摘 要： | 研究了线性离散不确定系统的鲁棒容错控制问题。针对线性离散控制系统存在不确定性和传感器失效的情况，利用降维观测器估计系统的状态，并基于估计的状态构成鲁棒容错控制律。给出了闭环系统具有鲁棒容错特性的充分条件。数值算例表明了算法的有效性。

| Abstract: | The robust fault-tolerant control problem is studied for uncertain linear discrete systems. A sufficient condition of robust stability for uncertain linear discrete systems with sensor failures based on a reduced order state observer is proposed. Also the design method of robust fault-tolerant controller is discussed. A numerical example is given to illustrate the design procedure and its effectiveness. |
