摘　　要：为了在系统出现故障时及时地整合资源以完成飞行任务,要求机载设备能够迅速地诊断和定位故障。采用故障树分析法对电动静液作动器(EHA-VS)的各种故障进行了分析,并且根据分析结果为系统设计了故障诊断和管理模块同时提出了一种对传感器信号进行分类编码的方法,实现了故障的快速诊断。In order to integrate the resources to complete the flight tasks when the faults occurred in the system, the airborne equipments should be able to diagnose and locate the faults as soon as possible to achieve the real-time requirement. Fault tree analysis was introduced to carry out a variety of faults analysis on the electro-hydrostatic actuator system, a fault diagnosis and management module was implemented based on the experimental results. The sensors signal categories and the encoding method were conceptualized, which can achieve the rapidly and effectively diagnosis of the faults in electric hydrostatic actuator system.
