摘　　要：故障诊断的模糊Petri网模型,将Petri网和模糊推理相结合建立。其中,用FPN表示模糊产生规则,用Petri网的变迁激活规则进行故障诊断推理,从而分析出异常行为过程间的因果关系,推理出故障的原因及其可信度以某型飞机电力启动系统故障为例,用模糊Petri网对其进行故障诊断,结果证明该技术可行有效。The Petri net and fuzzy reasoning were combined to establish the fuzzy Petri net model of fault diagnosis. The FPN was used to express fuzzy generated rules and the flux activation rules of Petri net were adopted to carry out the fault diagnosis reasoning; therefore, the cause and effect relationships in abnormal activity process were analyzed; then, the reasons and reliability of faults were reasoned. The fault diagnosis was applied in a certain plane electrics start system and the validity of this technology was proved.
