Application of vague method of faults diagnosis for diagnosis of vibration faults
Fujin Zhang · Computer Engineering and Applications Journal · 2011
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)=(1/n)integer ((3-|fhi(m)-fgi(m)|-|chi(m)-cgi(m)|-|dhi(m)-dgi(m)|)/(3+|fhi(m)-fgi(m)|+|chi(m)-cgi(m)|+|dhi(m)-dgi(m)|)) from i=1 to n is presented.To diagnose the vibration faulty of turbo generator by application of the vague method of faults diagnosis,the effect is ideal.
