Intermittent generalized synchronization in unidirectionally coupled systems with different topology of attractors

Intermittency near the boundary of generalized synchronization in unidirectionally coupled chaotic systems with different topology of attractors is studied. On–off intermittency is shown to be observed both in the case of the influence of the system with a simple topology of attractor on the system with a complex topology and, vice versa, in the case of the influence of the system with a complex topology of attractor on the system with a simple topology. Unidirectionally coupled Rössler and Lorenz systems and radiotechnical generators with 1.5 number of degrees of freedom have been considered as sample systems. Mechanisms resulting in the on–off intermittency appearance have been discussed.
