Abstract
A method is proposed for constructing the Volterra approximating model of a nonlinear dynamical system in the time domain using polyimpulse test signals of different amplitudes. The method is based on the application of the regularized least squares method and the choice of the optimal step size for the amplitude of the test signals, which increases the accuracy and computational stability of the identification procedure.
