Hyperbolic chaos and quasiperiodic dynamics in experimental nonautonomous systems of coupled oscillators

In the present paper in radiophysical experiments two different ways of destruction of invariant torus are shown. In the first case formation of chaotic attractor from four-frequency quasiperiodic torus involving torus doubling bifurcations is presented. In the second transformation of two-frequency torus into hyperbolic chaotic attractor was observed.
