| Qualitative numerical methods are used to study the evolution of a phase portrait of a pendulum mathematical model under the action of a periodic moment described by a nonlinear nonautonomous three-parameter differential equation. Attraction domains of 2?- and 4?-steady-state periodic modes are investigated. |
