Mathematical macromodeling of dynamic systems and examples of macromodels
(Publishing House of Lviv Polytechnic National University, 2006) Matviychuk, Yaroslav
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.
Numerical synthesis of the macromodel of generator with soft excitation of oscillations with the help of the second method of Lyapunov
(Видавництво Національного університету «Львівська політехніка», 2004) Matviychuk, Yaroslav
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.
