Analysis and Design of Expert System for Fault Diagnosis Based on Fuzzy Measurements

The structure and characteristics of fault diagnosis expert system are introduced.In order to simplify the input process,a new method of input signal conversion based on fuzzy theory is presented in this paper.The method of knowledge collection and the model of expert rules used in the system are presented.A reasoning network is designed,and the reasoning algorithm based on CF model is implemented.The system is developed in Microsoft MFC environment.The results of application in the oxidation reactor show its good performance in fault diagnosis.
