Fault detection of dual redundant actuation system based on the fault modeling

  • 摘要: 针对双余度舵机系统结构复杂、故障诊断困难的问题,提出了根据故障模型反向推理的故障诊断方法.在充分考虑各元件失效机理的基础上,将故障注入闭环系统建立典型故障模型.故障模型仿真了不同元件故障如何导致系统性能下降甚至完全失效.基于故障模型的仿真结果,对可观测到的异常状况进行分类和逆向推理归纳出故障诊断方法,并利用数学公式对一些故障量化评估.该诊断方法涵盖系统各元件,可快速定位故障元件,判断失效原因并进行定量分析,而且算法简单易于工程实现.
