Abstract: The problem of neural network modeling of nonlinear dynamic objects using recurrent neural networks is considered. An approach to improve the accuracy of modeling using a static neural network of the «multilayer perceptron» type, that processes correlation dependencies of a dynamic process and approximates the modeling error, is proposed. A technique for synthesis and application of the correlation neural network model CCF-MLP improving the quality of modeling of a conventional recurrent neural network, is formulated. Simulation experiments are carried out with a neural network recurrent network of the GRU type, that models the behavior of a nonlinear dynamic object, as well as GRU with the proposed CCF-MLP model. The improvement in the quality of modeling (RMSE, MAPE) is confirmed in the case of using CCFMLP both in the presence and absence of noise in the observed data. The practical applicability of the proposed method was tested on a real liquid level control system.

Keywords: cross-correlation function, multilayer perceptron, recurrent neural network, dynamic object modeling, nonlinear dynamic object
