Petri网作为一种图形化的网络与建模工具,能方便的表示和分析信息流,进行逻辑关系的表达和系统行为的建模,在故障检测和诊断领域得到越来越广泛的应用。该文对基于Petri网的故障诊断方法进行了系统研究,旨在为工程实践提供理论基础。
As a graphical network and modeling tool, Petri nets can represent and analyze information flow conveniently, and express logic relations and modeling of system behavior. Petri nets are more and more widely used in fault detection and diagnosis. This paper systematically studies the fault diagnosis method based on Petri net, aiming to provide theoretical basis for engineering practice.
