讨论了控制舵面／作动器故障的类型及它们对系统的影响，给出了故障检测和隔离系统的结构和工作原理，特别讨论了检测和隔离具有相似特征的舵面缺损故障的检测滤波器算法。理论分析和仿真验证表明，这种方法可以快速准确地得到故障类型及其影响大小的信息。 The types of control surface / actuator faults and their influence on the system are discussed. The structure and working principle of the fault detection and isolation system are given. In particular, the detection and isolation of detection and isolation of rudder defect with similar characteristics are discussed Algorithm. Theoretical analysis and simulation show that this method can quickly and accurately get the type of the fault and its impact on the size of the information.
