| 摘 要： | 传感器故障严重危害系统的可靠性，为此提出了一种针对传感器故障的容错控制方法。该方法以传感器的故障诊断为前提，从传感器功能冗余的定义出发，进行功能冗余分析，并利用调整观测器增益阵参数的办法来实现容错。仿真实验证明了该方法的有效性。

| Abstract: | The sersor failure damages system reliability seriously. A method of fault-tolerant control for sersor failure is provided. The method bases on sensor fault diagnostics. First, the functional redundancy was definited. Then, functional redundancy of sensors in control system was analysed. By tuning the parameters of observer gain matrix, control system can tolerate sensor failure. An example and its simulation results proved the effectiveness of the proposed method. |
