摘要
以二阶类Kuramoto振子为基础,构建了一类带有权重指数的振子网络模型,重点研究了权重指数对以振子为节点的网络同步能力的影响.通过数值仿真结果发现,频率指数的奇偶性对振子网络的同步能力有很大的影响.在频率取值形式一定的条件下,当耦合频率指数为偶数时,振子网络的同步能力增强,而当耦合频率指数为奇数时,振子网络的同步能力减弱.
Based on the second-order Kuramoto-like oscillatory model,a complex network model with weighting exponent is presented in this paper.Moreover,the impact of exponent on synchronizability of oscillatory network is investigated via numerical simulations.It shows that the characteristics of coupling have great effects on the synchronziability of power network.We found that the even coupling-frequency enhance the synchronizability.On the contrary,the odd weighting-frequency exponent reduces the synchronizability of oscillatory network.
