Petri网模型在故障诊断领域的应用研究

Study on the Application of Petri Nets to Fault Diagnosis

结合故障诊断问题的特点 ,在基于 Petri网基本原理的前提下 ,对Petri网在故障诊断领域的应用问题进行了研究 ,建立了故障传播、故障诊断网模型 ,对不确定逻辑关系的 Petri网模型进行了研究 ,拓展了网的描述能力 。

Based on the character of the Fault diagnosis and the theory of the petri nets,the application of the petri nets to fault diagnosis is studied.The models of fault propagation,diagnosis and the fuzzy logical petri net are established. The representation capability of the petri net is extended, and it is important to modelling for fault diagnosis.
