Research of network synchronization based on three-dimensional chaotic system

The network synchronization of a three-dimensional chaotic system with hyperchaotic characteristics is studied in this paper. The synchronization properties of the network is analyzed with nonlinear coupling, also the synchronization conditions of the fully connected network and star network are researched. For fully connected network, symmetric non-linear coupling method is adopted to achieve its network synchronization. As for star network, its network synchronization is realized by using unidirectional non-linear coupling. Finally, numerical simulation proves the validity of the methods.
