摘要:

在本文中,我们研究了一个系统的两个Rossler振荡器耦合通过一个时变的链接,周期性地切换之间的两个值。我们分析了系统的行为相对于切换的频率。通过应用平均技术的假设下,一个高的开关频率,我们发现,虽然每个值的耦合不产生同步,在高频率的两个之间的切换稳定的同步流形。然而,我们也发现窗口的同步低于该技术预测的值,我们开发了一个主稳定性函数来解释这些窗口的外观。系统的谱特性是理解系统动力学特性和开关频率区间内同步失效的有效工具。数值和实验结果与分析一致。

英文摘要:

In this paper, we study a system of two Rossler oscillators coupled through a time-varying link, periodically switching between two values. We analyze the system behavior with respect to the frequency of the switching. By applying an averaging technique under the hypothesis of a high switching frequency, we find that although each value of the coupling does not produce synchronization, switching between the two at a high frequency stabilizes the synchronization manifold. However, we also find windows of synchronization below the value predicted by this technique, and we develop a master stability function to explain the appearance of these windows. Spectral properties of the system are a useful tool for understanding the dynamical properties and the synchronization failure in some intervals of the switching frequency. Numerical and experimental results in agreement with the analysis are presented.
