A Fuzzy Petri Net Model for Fault Diagnosis

摘要

According to the characteristics of the fault diagnosis for a Petri net, a fuzzy Petri net model for fault diagnosis is presented.The matrix format and the rule of transition enabling and firing were modified and defined properly.Fault fuzzy diagnosis and reasoning were carried out with simple matrix and set computation procedures.And the firing rule of the fuzzy Petri net model was reflected adequately in the algorithm.Last, the validity of the model and the algorithm was proved by an example of gas turbine fault diagnosis.
