关于耦合非线性振子的Kuramoto模型的稳定性

On the stability of the Kuramoto model of coupled nonlinear oscillators

Ali Jadbabaie, Nader Motee, Mauricio Barahona

摘要:

我们提供了一个分析的经典仓本模型的耦合非线性振荡器,超越了现有的结果,所有到所有的网络相同的振荡器。我们的工作适用于任意互连拓扑的振荡器网络的不确定的自然频率。利用谱图论和控制理论的工具,我们证明了对于临界值以上的耦合,同步状态是局部渐近稳定的,导致所有的相位差收敛到一个恒定的值,无论是在相同的自然频率的情况下,以及不确定的。我们进一步解释了系统的行为作为振荡器的数量增长到无穷大。

英文摘要:

We provide an analysis of the classic Kuramoto model of coupled nonlinear oscillators that goes beyond the existing results for all-to-all networks of identical oscillators. Our work is applicable to oscillator networks of arbitrary interconnection topology with uncertain natural frequencies. Using tools from spectral graph theory and control theory, we prove that for couplings above a critical value, the synchronized state is locally asymptotically stable, resulting in convergence of all phase differences to a constant value, both in the case of identical natural frequencies as well as uncertain ones. We further explain the behavior of the system as the number of oscillators grows to infinity.
