| 摘 要： | 针对导弹姿态控制系统的故障情况,阐述了一种利用基于滑模观测器的故障诊断方法.该方法主要是对保持观测器处于滑动模态的等效输出注入进行分析.通过对观测器输出的正确分析,可以达到对故障的正确估计,避免故障误报和漏报.通过一仿真算例,证明了该方法的有效性.

| Abstract: | In respect of the fault diagnosis research in missile control systems,a fault detection approach with sliding mode observer is provides.The equivalent output injection signal required to maintain the observer in a sliding motion is essentially analyzed in this method,and appropriate analysis of the observer output is shown to be efficient to the estimation of the faults with no false or missed detections.The effectiveness of this method is proved by a simulation results.As a way for fault diagnosis,this method shows its foreground of future application. |
