复杂网络连接的Chen系统的同步化

利用Chen系统的有界性和挤压性质,提出了一种新的研究网络同步化的方法．选取以N个Chen系统作为结点的4种复杂网络(环形网络、星形双向耦合网络、小世界网络、全局耦合网络)作为研究对象,理论推导得出网络中Chen系统同步需满足的参数条件．通过比较证明了小世界网络具有易于同步和结构简单的优点,数值仿真结果与理论分析相一致．

Synchronization of Chen Systems in Complex Networks

In this paper,we present a new way for researching the monotonous synchro- nization of chaotic systems in the complex networks.The method proposed here is based on the boundary and squeezing properties about Chen system.We study four complex networks, including ring network,star network,small-world network and globally coupled network,which all have N Chen systems.By theoretic inducing,we derive the sufficient conditions for syn- chronization,and prove that the small-world network is better than others by comparison.The result of numerical simulations is consistent with the theory.
