| 摘 要： | 复杂系统的故障具有模糊性与精确性的复杂特性,精确的推理方法难以有效地对复杂特性的故障进行诊断。提出模糊产生式规则与Petri网推理技术相结合的故障诊断模型,以研究模糊故障的推理诊断方法。以某发射装置控制系统为研究对象,给出一个复杂特征故障的诊断实例。研究结果表明,模糊产生式规则Petri网模型方法可以有效地对复杂系统的模糊性与精确性双重特征的故障进行推理诊断。

| Abstract: | Faults of complex system feature complex characteristic of the fuzzy and the precision. A precise fault diagnosis model is hard to handle the complicated characteristics of system faults. A fault diagnosis model combined fuzzy generating rule with reasoning technique of Petri net is presented to study the method of fuzzy fault diagnosis. An example of complex fault diagnosis with the control system of a lunch-equipment is given. It is shown that the model of fuzzy generating rule with Petri net can diagnose faults of fuzzy and precision of complex system effectively. |
