模糊Petri网在液压泵故障诊断中的应用研究

摘要

Hydraulic system failure diagnosis has become worldwide research subject. How to diagnose the causes and position of fault fast and accurately is the problem that many experts study. Fuzzy Petri net was introduced into hydraulic diagnostic system as reasoning mechanism to judge the causes and location of failure. The application of fuzzy Petri net in hydraulic pump fault diagnosis was illustrated.%液压系统的故障诊断已经成为世界性的研究课题,如何快速、准确地诊断出故障的原因和位置,也是许多专家研究的问题.在液压诊断系统中引入模糊Petri网作为推理机制来判断故障的原因和位置,并具体介绍模糊Petri网在液压泵诊断过程中的应用.
