The New Higher Order Spectral Techniques for Non-Linearity Monitoring of Structures and Machinery

Research output: Chapter in Book/Report/Conference proceeding › Conference contribution › peer-review

Abstract

The new higher order spectral techniques, the normalized cross-covariances of complex spectral components, are proposed for monitoring structure and machinery non-linearity and signal non-Gaussianity and estimating the harmonic phase coupling of signals from structures and machines. Normalization of the proposed techniques is also developed. It is shown by simulation that the proposed techniques provide effectiveness gain for detection of non-linearity in comparison with the HOS.
