摘要: 提出模糊数据[hij]化成Vague数据[hij]的转化公式:[Ki(hj)=hij=[tij,1-fij]=(hij)2,(hij)1/2],以及Vague集[H]和[G]之间的相似度量公式:[Mm(H,G)=1ni=1n3-f(m)hi-f(m)gi-c(m)hi-c(m)gi-d(m)hi-d(m)gi3+f(m)hi-f(m)gi+c(m)hi-c(m)gi+d(m)hi-d(m)gi]。应用Vague故障诊断方法,进行汽轮发电机组的振动故障诊断,其效果是理想的。

Abstract: A transforming formula from fuzzy data [hij] to vague data [hij]:[Ki(hj)=hij=[tij,1-fij]=(hij)2,(hij)1/2] is presented.And a similarity measure formula between two vague sets [H]and [G]:[Mm(H,G)=1ni=1n3-f(m)hi-f(m)gi-c(m)hi-c(m)gi-d(m)hi-d(m)gi3+f(m)hi-f(m)gi+c(m)hi-c(m)gi+d(m)hi-d(m)gi] is presented.To diagnose the vibration faulty of turbo generator by application of the vague method of faults diagnosis,the effect is ideal.

Key words: Vague set, Vague method of faults diagnosis, transforming formula of data, similarity measure formula, diagnosis of vibration faults
