The problems of macromodeling of continuous nonlinear dynamic systems with lumped constant parameters are considering. The common modeling structure in the form of the system of ordinary differential equations is shown. The regularised methods of its identification are described. The examples of macromodels of different complexity and nature are given.

Theoretical substantiation of a method for providing the convergence of a solution of mathematical model of an independent system to a given solution with the help of the
second method of Lyapunov is considered. The method is illustrated by model of the self-oscillator, for which the conditions of "soft" excitation of oscillations are provided.
