Dynamical System Identification Using Wavelet Transform
Ren Yi-Chun, Deng Shouchang · Natural Science Journal of Xiangtan University · 2004
The wavelet transform is used as a time-frequency representation for system identification. The impulse response of the dynamical system is analyzed by Morlet wavelet.The frequencies and viscous damping ratios are obtained by the ridges of the wavelet coefficients.
