Application of Three Order Cumulants in Fault Diagnosis

Abstract:

Compared with bispectrum, three-order cumulants have a lower computing complexity, in the experiment, features of fault signals and normal signals are fetched by 2-D wavelet in different directions, then these features are used to diagnose fault. The experiment shows, that the method can achieve satisfactory result through different selections in fault diagnosis. the results prove that the method in the experiment is necessary.
