耦合准同振子网络的同步稳定性

Synchronization Stability of Coupled Near-Identical Oscillator Network

Jie Sun, Erik M. Bollt, Takashi Nishikawa

摘要:

我们导出了分析耦合近全同振子同步稳定性的变分方程。为了研究参数失配对稳定性的影响,我们定义了主稳定性方程和相关的主稳定性函数,它们与网络结构无关。特别是,我们提出了几个例子,耦合近相同的洛伦兹系统配置在小网络(环图和序列网络)与固定的参数不匹配和一个大的Barabasi-Albert无标度网络与随机参数不匹配。我们发现,几种不同的网络架构允许类似的结果,尽管各种不匹配的模式。

英文摘要:

We derive variational equations to analyze the stability of synchronization for coupled near-identical oscillators. To study the effect of parameter mismatch on the stability in a general fashion, we define master stability equations and associated master stability functions, which are independent of the network structure. In particular, we present several examples of coupled near-identical Lorenz systems configured in small networks (a ring graph and sequence networks) with a fixed parameter mismatch and a large Barabasi-Albert scale-free network with random parameter mismatch. We find that several different network architectures permit similar results despite various mismatch patterns.
