模糊Petri网在电站燃气轮机故障诊断中的应用

Application of Fuzzy Petri Net in Fault Diagnosis of Gas Turbine

本文给出了用模糊 Petri网模型来表示燃气轮机故障诊断专家系统中模糊产生式知识库的方法。并在这个模型的基础上 ,给出了有效的推理算法 ,并举例验证其正确性和在燃气轮机专家系统中应用的可行性。

This paper presents a fuzzy Petri net modal (FPN) to represent the fuzzy production rules of a rule base system.Based on the fuzzy Petri net modal,an efficient fault diagnostic reasoning algorithm is proposed.Its accuracy and feasibility in a gas turbine diagnosis system is verified.
