Consideration was given to the model obeying a system of ordinary differential equations
where the subsystems are systems of autonomous ordinary differential equations. If the
coupling parameter ε = 0, then the model falls apart into decoupled subsystems. For a model
consisting of coupled subsystems, considered was the main mode for which the problems of
oscillations, bifurcation, and stability were solved, and the results obtained before for the case
of two second-order subsystems were generalized.
