摘要
故障诊断是离散事件系统中一项重要的研究内容,对于保障系统安全具有积极意义。基于Petri网的故障诊断相关研究主要分为故障可诊断性研究以及故障诊断器的构造理论研究,故障可诊断性又可以进一步分为一般可诊断性与K-可诊断性,而故障诊断器的设计方法又可以按照适用系统类型进一步分类。综述了故障诊断理论中可诊断性、K可诊断性的各类研究方法和研究结论,介绍了离散Petri网系统、连续Petri网系统和分布式Petri网系统中故障诊断器的设计方法,并对各类方法的特点进行了重点分析。最后,给出了基于Petri网的故障诊断进一步研究的方向与应用难点,其对今后研究有一定的指导意义。
Fault diagnosis is an important research aspect in the area of discrete event system,which has great value to ensuring the safety of systems.Research on fault diagnosis based on Petri nets can be mainly divided into two classes,which are the study on diagnosiability theory and the study on the theory of fault diagnoser constructing algorithm.Similarly,the diagnosiability research can be divided into two aspects：diagnosiability and K-diagnosiability,while fault diagnoser constructing algorithm can also be further classified according to applying systems.Various study methods and conclusions for diagnosability and K-diagnosiability of fault diagnosis were reviewed,and the constructing methods of fault diagnoser in discrete Petri nets systems,continuous Petri nets systems and distributed Petri net systems were introduced,and their characteristics were analyzed in detail.Finally,the research directions and application problems for further study were discussed,which can provide directive significance.
