Annotation | The article deals with a system of differential equations with a cylindrical phase space. For it, using the torus principle, conditions for the existence of limit cycles of the first kind are formulated. For the considered system, a numerical analysis of the scenario of bifurcations of a stable limit cycle is performed depending on the parameters of the system. The question of the number and methods of detection of unstable cycles arising as a result of bifurcation is considered. |

Keywords | system of differential equations, torus principle, limit cycle of the first kind, bifurcation, unstable cycle |
