耦合几乎相同振子的同步优化网络及其结构分析

Synchronization optimized networks for coupled nearly identical oscillators and their structural analysis

Suman Acharyya, R. E. Amritkar

摘要:

讨论了主稳定函数(MSF)在分析耦合近全同振子广义同步稳定性中的推广。耦合振子的几乎相同的性质来自于某些参数失配,而动力学方程对于所有振子都是相同的。从MSF的稳定性判据出发,构造了具有较好同步性能的最优网络,即MSF网络. e.同步对于最宽可能范围的耦合参数是稳定的。在优化后的网络中,选择参数值处于一端的节点作为枢纽。在优化后的网络中,具有较大参数差异的节点对优先用于创建链路。优化后的网络是离散的,即网络的最优解。e.度高的节点倾向于与度低的节点连接。

英文摘要:

The extension of the master stability function (MSF) to analyze stability of generalized synchronization for coupled nearly identical oscillators is discussed. The nearly identical nature of the coupled oscillators comes from some parameter mismatch while the dynamical equations are the same for all the oscillators. From the stability criteria of the MSF, we construct optimal networks with better synchronization property, i. e. the synchronization is stable for widest possible range of coupling parameter. In the optimized networks the nodes with parameter value at one extreme are selected as hubs. The pair of nodes with larger parameter difference are preferred to create links in the optimized networks. And the optimized networks are found to be disassortative in nature, i. e. the nodes with high degree tend to connect with nodes with low degree.
