摘要:

针对一类满足利普希茨条件的离心式压缩机系统,提出了一种新型压缩机执行器故障诊断方法。设计自适应诊断观测器,实时动态采集压缩机执行器故障前后的信息,对压缩机执行器故障进行精确跟踪,达到故障诊断的目的。利用Lyapounov函数分析了设计系统的稳定性。仿真结果表明,自适应诊断观测器能够实时精准的跟踪离心式压缩机执行器故障,证明了该方法的有效性。

A novel compressor actuator fault diagnosis method is proposed for the centrifugal compressor system satisfying Lipschitz condition. By collecting the real-time status of the compressor actuator faulty and normal conditions, adaptive diagnostic observer is design, and then the compressor actuator fault is tracked accurately, which realizes the fault detection. The stability of design system is analyzed by using Lyapounov function. The results show that the adaptive fault diagnosis observer can accurately track the centrifugal compressor actuator fault, which proves the effectiveness of the proposed method.
