Synchronized states in chaotic systems coupled indirectly through a dynamic environment

V. Resmi, G. Ambika, R. E. Amritkar

摘要:

我们考虑通过一个共同的混沌网络间接耦合的混沌系统的同步,其中环境具有通过系统的反馈调制的其自身的内在动力学。我们发现,同步行为的丰富多样性,如同相、反相、完全和反同步都是可能的。我们提出了一个近似的稳定性分析不同的同步行为。过渡到不同状态的同步行为进行了分析,在参数平面的耦合强度的数值研究,如Rossler和Lorenz系统的具体情况下,其特征在于使用各种指标,如相关性,平均相位差和李雅普诺夫指数。数值分析得到的阈值条件与稳定性分析得到的阈值条件一致。

英文摘要:

We consider synchronization of chaotic systems coupled indirectly through a common environmnet where the environment has an intrinsic dynmics of its own modulated via feedback from the systems. We find that a rich vareity of synchronization behavior, such as in-phase, anti-phase,complete and anti- synchronization is possible. We present an approximate stability analysis for the different synchronization behaviors. The transitions to different states of synchronous behaviour are analyzed in the parameter plane of coupling strengths by numerical studies for specific cases such as Rossler and Lorenz systems and are characterized using various indices such as correlation, average phase difference and Lyapunov exponents. The threshold condition obtained from numerical analysis is found to agree with that from the stability analysis.
