摘要
文中介绍了主元分析算法以及在故障检测方面的应用。利用此方法来检测飞控系统作动器卡死故障。应用实例表明该算法对作动器卡死单一故障和组合故障能够准确识别,并对故障的定位也取得较好的效果。
In this paper, the principle component analysis（PCA） theory is introduced, and the theory is used for fault diagnosis of lock of actuator. The result of simulation indicates the method can accurately identify single faults and complex faults, and can locate the fault exactly.
