摘要：

我们提出了一种方法来分析扩散耦合多稳态系统的合奏同步。首先，我们研究了两个双向耦合多稳态振子如何同步，并证明了共存同步态吸引域的高度复杂性。然后，我们建议使用的主稳定性函数（MSF）的多稳态系统来描述同步性，即使在间歇性行为，网络的多稳态振荡器，无论耦合振荡器的数量和相互作用的结构。特别是，我们表明，一个网络的多稳态元素是同步的拓扑谱和耦合强度的给定范围内，无论特定的吸引子动态，不同的振荡器被锁定，甚至在存在的不稳定性。最后，我们通过实验证明了MSF方法的可行性和鲁棒性与网络的多稳态电子电路。

英文摘要：

We propose a methodology to analyze synchronization in an ensemble of diffusively coupled multistable systems. First, we study how two bidirectionally coupled multistable oscillators synchronize and demonstrate the high complexity of the basins of attraction of coexisting synchronous states. Then, we propose the use of the Master Stability Function (MSF) for multistable systems to describe synchronizability, even during intermittent behaviour, of a network of multistable oscillators, regardless of both the number of coupled oscillators and the interaction structure. In particular, we show that a network of multistable elements is synchronizable for a given range of topology spectra and coupling strengths, irrespective of specific attractor dynamics to which different oscillators are locked, and even in the presence of intermittency. Finally, we experimentally demonstrate the feasibility and robustness of the MSF approach with a network of multistable electronic circuits.
