Identification of nonlinear systems is one of the most difficult tasks. The article reveals the shortcomings of the classical approach to system identification. Given the non-linear model of the hydromechanical system is described. The problems of estimating the model parameters are revealed. The neural network approach for solving the problem of estimating the parameters of nonlinear systems is proposed. The schemes of an artificial neural network implementation are considered. Results of artificial neural network simulation for different operating modes are described. The analysis of the simulation results is described.
