自适应耦合网络中的脉冲混沌同步

Pulsed chaos synchronization in networks with adaptive couplings

Marco Winkler, Sebastian Butsch, Wolfgang Kinzel

摘要:

具有静态耦合的混沌单元网络可以同步到一个公共的混沌轨道。研究了动态自适应耦合对混沌网络合作行为的影响。耦合通过两种竞争机制来调整其两个单元的活动:耦合强度的指数下降通过由于去同步活动而增加来补偿。这种机制阻止网络达到稳定状态。耦合映象格子的数值模拟显示了相互同步的簇的脉冲中断的非同步单元的混沌轨迹。这些脉冲发生在所有尺度上,有时扩展到整个网络。同步单元的集群可以由一小组同步单元触发。

英文摘要:

Networks of chaotic units with static couplings can synchronize to a common chaotic trajectory. The effect of dynamic adaptive couplings on the cooperative behavior of chaotic networks is investigated. The couplings adjust to the activities of its two units by two competing mechanisms: An exponential decrease of the coupling strength is compensated by an increase due to de-synchronized activity. This mechanism prevents the network from reaching a steady state. Numerical simulations of a coupled map lattice show chaotic trajectories of de-synchronized units interrupted by pulses of mutually synchronized clusters. These pulses occur on all scales, sometimes extending to the entire network. Clusters of synchronized units can be triggered by a small group of synchronized units.
