Abstract :
In this paper a MR vibrating semi-active control system has been built, an AR(10) model was established with colored noises from the output signals. Comparisons between power spectrum from second order moment function and bispectrum, trispectrum has been made, the later gives an indication of the correlation between the phases of different frequency components. Since time series model is a parametric model, the reconstructed bispectrum and power spectrum are smooth. It is demonstrated that the higher order spectrums are effectively for recognition and description of the nonlinear systems.
