Abstract

Based on wavelet multiresolution analysis theory, this paper proposes a two-step identification method for multirate sampled-data systems. First the problem of multirate sampled-data consistent reconstruction is studied, then a new weighted band-wise identification method is proposed. This method has the advantages of noise-free, convenient modeling of the interesting band of plant precisely, and easy incorporation with system design. Simulation results are given to illustrate that this two-step identification method is effective and feasible in process modeling
