摘要
讨论鲁棒辨识问题．基于离散小波变换，提出分段频带逼近，估计频域模型误差界（幅值）．首先介绍离散小波变换，然后给出分段频带逼近算法，仿真结果验证所提方法．
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.
