Synchronization phenomena on four simple chaotic oscillators full-coupled by capacitors <Abstract> Synchronization in simple chaotic oscillators full-coupled by capacitors with tetrahedron structure is investigated. An simple three-dimensional autonomous circuit is considered as a chaotic sub-circuit. We consider two types of systems by changing coupling points. By carrying out numerical simulations and circuit experiments, entirely different synchronization modes can be observed. Further, We pay attention to the region where attractor is and the shapes of attractors generated by each chaotic oscillator to investigate synchronization states and bifurcation to synchronization of chaos. In the proposed systems, there are many interesting synchronization and bifurcation phenomena including different types of synchronization from results reported before. |
