摘要
根据Lyapunov稳定性理论,分别给出了环状网络和全局耦合网络渐近同步和指数同步的充分条件.并对两种不同结构网络的同步性能进行了比较,发现全局耦合网络同步性能更好.最后以Lorenz混沌系统为节点,分别对4个节点的环状网络和全局耦合网络的混沌同步进行了数值仿真,验证了结论的可靠性.
Based on Lyapunov stability theorem,the sufficient conditions of asymptotical synchronization and exponential synchronization for networks with ring topology and global coupling topology are given.The synchronizabilities of ring connection and global connection are compared;and the conclusion is that the global connected networks have stronger synchronizability.Finally,the result of numerical calculation for the ring connected and global connected networks with 4 Lorenz nodes shows that the theorem is reliable.
