摘要:

我们提出并实验证明了一种技术,即使当耦合强度是未知的和随时间变化的任意网络的混沌振荡器,实现和保持一个全局状态的相同的同步。在每个节点处,自适应同步算法动态地估计到该节点的网络耦合信号的电流强度。我们的实验表明,该计划在一个网络的三个双向耦合的混沌光电反馈回路,我们目前的数值模拟显示其在更大的网络中的应用。通过主稳定性函数方法分析了任意耦合拓扑的同步状态的稳定性。

英文摘要:

We present and experimentally demonstrate a technique for achieving and maintaining a global state of identical synchrony of an arbitrary network of chaotic oscillators even when the coupling strengths are unknown and time-varying. At each node an adaptive synchronization algorithm dynamically estimates the current strength of the net coupling signal to that node. We experimentally demonstrate this scheme in a network of three bidirectionally coupled chaotic optoelectronic feedback loops and we present numerical simulations showing its application in larger networks. The stability of the synchronous state for arbitrary coupling topologies is analyzed via a master stability function approach.
