Study on fuzzy fault diagnosis for complex systems

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.
