摘要：
A problem of structure identification of nonlinear dynamic systems on the set of continuous block-oriented models with nonlinear elements in the form of polynomial functions of finite degree and stable linear elements in the frequency domain is considered. Method of structure identification in steady state based on the observation of the system's input and output variables at the input sinusoidal influences is proposed. The problem of the structure identification is considered according to the classical definition of identification of Zadeh. The structure definition criterion of the model is developed. The identification method is investigated by theoretical analysis and computer modelling. (C) 2019, IFAC (International Federation of Automatic Control) Hosting by Elsevier Ltd. All rights reserved.
