Study on Aeroengine Fault Diagnosis Based on Similarity Measures between Vague Sets

Aim at the localization of traditional fault diagnosis,this paper discussed the approach of aeroengine fault diagnosis based on similarity measures between Vague Sets.The similarity measures between Vague Sets was combined with aeroengine fault diagnose problem.On the base of gaining the relation of fault omen and fault type,counted the analogical degree between the diagnosing fault swatch Vague Set and system fault knowledge Vague Set,so as to diagnose and arrange the faults.Through an example to illustrate that the application of this approach to some aeroengine fault diagnosis,and the result showed its conveniency and veracity,as well as the efficiency and rationality in the aeroengine fault diagnosis based on similarity measures between Vague Sets.
