Comparison of Non-linear Signals Analysis Methods

摘要：

　　In modern engineering,linear is relative,while non-linear and non-stationary is absolute.There are many methods in non-linear signals processing.How to select a most suitable analysis method quickly for the nonlinear signal is particularly important,which can improve the signal processing efficiently.In this paper,three common analysis methods for nonlinear signals,Wavelet spectrum,Hilbert spectral analysis(HSA)and Poincaré mapping are researched and analyzed by some typical nonlinear signals from the complex electromechanical model test system.The effectiveness and application scopes of these approaches are obtained,which can provide a theoretical and practical basis for engineering application.
