基于模型故障诊断方法的仿真研究

Study on Simulation of the Model-based Fault Diagnostic Methodology

介绍了一种以典型的电液控制系统为目标 ,利用SIMULINK平台的仿真功能 ,虚拟化地再现了该控制系统及其几种常见的故障的虚拟故障诊断实验系统。通过系统模型和虚拟故障系统的输出特性对比 ,直观地描述了基于模型故障诊断方法的全部环节。

This paper presents a virtual fault diagnosis experimental system. The electro-hydraulic system and some of faults can be simulated by the SIMULINK tools. The fault diagnosis model-based is described directly by comparing the output characteristic of system model and virtual fault system.
