A new method of choosing scales in wavelet transform for damping identification
Wang Ben-li · 哈尔滨工业大学学报：英文版 · 2008
A systematic study of the method of selecting scales in wavelet transform for damping identification in frequency domain was carried out. A method to select the scale with the modulus at the maximum was developed by extending the range of scales. It is proved that using this method in small damping ratio and linear system, we can achieve better results in identification of the closely-spaced model.
