Application of Fuzzy Control Theory in expert systems

The Fuzzy Control Theory was applied to the expert system can achieve very good results. This paper introduces basic theories and implementation approaches about two kind of mathematical model which are applied to Fault Diagnosis System with Fuzzy Control Theory according to engineering practice. This paper also illustrates that creating Knowledge Base System with Fuzzy Comprehensive Judgment and diagnosing fault with Fuzzy Fault Diagnosis will receive excellent effect. Fuzzy Control Theory, Fuzzy Matrix, Fuzzy Comprehensive Judgment, Fuzzy Fault Diagnosis, expert systems.
