The engineering software tools for nonlinear dynamical systems identification based on Volterra models in frequency domain

Abstract

Abstract—The engineering software tools used for nonlinear dynamical systems nonparametric identification based on Volterra models in frequency domain is presented. The polyharmonic test sequences with different amplitudes are used for test procedures. The wavelets application for filtering of measurement noises of received responses and characteristics of the identifiable system allowed enlarging computational stability of the identification method. The proposed methodology and the software tools applied for construction of the communication channel models.
