Natural frequencies and damping estimation using wavelet transform of a frequency response function

This paper deals with a general wavelet transform of FRFs for linear systems. Complex fractional functions are used as wavelets and properties of the wavelet transform are studied. Then an efficient method for estimating natural frequencies and dampings is proposed. The efficiency of the method is illustrated with both analytical and experimental data of frequency response functions.
