After summarizing the advantages and disadvantages of current integral methods, a novel vibration signal integral method based on feature information extraction was proposed.
This method took full advantage of the self-adaptive filter characteristic and waveform correction feature of ensemble empirical mode decomposition in dealing with nonlinear and nonstationary signals.
This research merged the superiorities of kurtosis, mean square error, energy, and singular value decomposition on signal feature extraction.
The values of the four indexes aforementioned were combined into a feature vector.
Then, the connotative characteristic components in vibration signal were accurately extracted by Euclidean distance search, and the desired integral signals were precisely reconstructed.
With this method, the interference problem of invalid signal such as trend item and noise which plague traditional methods is commendably solved.
The great cumulative error from the traditional time-domain integral is effectively overcome.
Moreover, the large low-frequency error from the traditional frequency-domain integral is successfully avoided.
Comparing with the traditional integral methods, this method is outstanding at removing noise and retaining useful feature information and shows higher accuracy and superiority.
