Study of self-oscillations in distributed-parameter Van der Pol oscillator

The authors study a mathematical model of a distributed-parameter analog of a Van der Pol oscillator, which is a linear system of telegraph equations with nonlinearity in one of the boundary conditions. The theol-etical study reveals a buffer phenomenon, i.e., simultaneous existence of several stable periodic regimes in the boundary-value problem under investigation. The results of the experiment confirming the feasibility of this phenomenon are described.
