利用逆系统的故障诊断方法

An Approach of Fault Diagnosis Using Inversion of System

故障诊断在现代控制系统中是一个重要的分支 .本文提出了一种新的故障诊断方法 ,利用系统的逆检测故障 ,并对故障源进行唯一定位且求出故障大小 .仿真和理论都证明了方法的正确性 .

Fault diagnosis is an important branch of modern control system.This paper presents a new approach of fault diagnosis,which makes use of the inversion of system to detect faults and can solely isolate the fault source and can get the magnitude of fault.The theory and simulation results show the correctness of this method.
