Nonautonomous dynamics of coupled van der Pol oscillators in the regime of amplitude death

A pulse driven system of two coupled van der Pol oscillators in the regime of amplitude death is studied. The existence of islands of quasiperiodic regimes on the parameter plane of period and amplitude of the external force is shown in numerical and electronic experiments. A number of different types of oscillations in this system are illustrated.

► We study pulsed driven system of coupled oscillators in the regime of amplitude death.
► We compare numerical and experimental results.
► The pulsed force can initiate quasiperiodic oscillations.
► At increase of the frequency detuning, the quasiperiodic regimes disappear.
