具有非均匀相互作用时滞的耦合大振子系统

Large coupled oscillator systems with heterogeneous interaction delays

Wai Shing Lee, Edward Ott, Thomas M. Antonsen

摘要:

为了发现非均匀通信延迟对耦合振子大系统动力学的一般影响,本文研究了一个包含交互延迟分布的Kuramoto模型的修正。通过将注意力集中在原系统的不变流形上的约化动力学上,我们推导出了系统的控制方程,我们使用它来研究非相干态的稳定性和从稳定非相干态到稳定相干态的动力学过渡行为。我们发现,分布函数的延迟可以大大改变系统的动力学。

英文摘要:

In order to discover generic effects of heterogeneous communication delays on the dynamics of large systems of coupled oscillators, this paper studies a modification of the Kuramoto model incorporating a distribution of interaction delays. By focusing attention on the reduced dynamics on an invariant manifold of the original system, we derive governing equations for the system which we use to study stability of the incoherent states and the dynamical transitional behavior from stable incoherent states to stable coherent states. We find that spread in the distribution function of delays can greatly alter the system dynamics.
