| Abstract: | This paper discusses the problem of robust identification. Band-wise approximation based ondiscrete wavelet transform is proposed for quantifying frequency-domain model error bounds (amplitude).First,the discrete wavelet transform is introduced. Then the band-wise approximation algorithm is addressed.Finally,some simulation examples are given for testing the proposed algorithm. |
