| 摘 要： | 基于稳定性理论，研究了中立型时滞系统对传感器失效具有完整性的鲁棒客错控制律的设计方法，得到了通过线性矩阵不等式（LMI）表示的系统渐近稳定的充分条件。在该容错控制器作用下，可以保证系统对传感器故障不敏感，仍能在一定的性能指标下稳定运行。仿真结果表明了本文设计方法的有效性。

| Abstract: | The problem of fault - tolerance control against sensor failures in linear state feedback systems is studied. Based on the Lyapunov stability theory , the design of state feedback control laws for neutral time delay systems with sensor failures is discussed. A sufficient condition for the system to be asymptotically stable is presented. The fault - tolerant controllers ensure that the system is not sensitive to sensor failures and that the system can run stably with certain satisfying performance. The simulation example is Also provided to demonstrate the effectiveness of the proposed design method. |
