A Fault Diagnosis Method Based on CFPN Model

摘要

In traditional FPN model, the matrix operations are too excessive and it does not meet the requirements of real-time in fault diagnosis system. The paper has improved the FPN model and proposed a CFPN (Controlled Fuzzy Petri Net) modeling method. This method has added controlled place in FPN and improved the design method of control arc of the control place. The method is based on the principle of p- and it enables to simplify the logic of FPN fault diagnosis. That can reduce the matrix computation in FPN fault diagnosis reasoning to improve the efficiency of fault diagnosis. This paper has applied the method in the distillation column fault diagnosis system and verified the applicability and effectiveness of fault diagnosis method based on CFPN model.
