Research of air heater fault diagnosis based on Fuzzy theory / 医疗卫生装备

ABSTRACT

This paper describes the basic theories and means of fuzzy logic fault diagnosis. Aiming at the faults that appears in air heater,the fuzzy relation matrix used for its fault diagnosis is constructed. Based on that,the air heater fault diagnosis examples are given. Application results show that it is feasible to apply the method of fuzzy diagnosis to diagnose air heater faults and the method is simple and valid.
