奇异非混沌吸引子同步的解析研究

An Analytical Study on the Synchronization of Strange Non-Chaotic Attractors

G. Sivaganesh, A. Arulgnanam

摘要:

在本文中,我们提出了一个分析研究中观察到的同步动力学单向耦合quasipherical-forced系统,表现出奇怪的非混沌吸引子(SNA)在其动态。通过相图和庞加莱映射分析研究了非耦合系统中观察到的SNA动力学。通过耦合驱动系统和响应系统的相似分段线性区域的状态方程得到差分系统。耦合系统的同步机制是通过差分系统的一个分段线性区域中的特征值的分叉来实现的。在差分系统的每个分段线性区域中的归一化状态方程的解析解已被用来解释同步动力学通过相图和时间序列分析。通过主稳定性功能确认同步状态的稳定性。一个明确的解析解解释的同步SNA的文献中首次报道。

英文摘要:

In this paper we present an analytical study on the synchronization dynamics observed in unidirectionally-coupled quasiperiodically-forced systems that exhibit Strange Non-chaotic Attractors (SNA) in their dynamics. The SNA dynamics observed in the uncoupled system is studied analytically through phase portraits and poincare maps. A difference system is obtained by coupling the state equations of similar piecewise linear regions of the drive and response systems. The mechanism of synchronization of the coupled system is realized through the bifurcation of the eigenvalues in one of the piecewise linear regions of the difference system. The analytical solutions obtained for the normalized state equations in each piecewise linear region of the difference system has been used to explain the synchronization dynamics though phase portraits and timeseries analysis. The stability of the synchronized state is confirmed through the Master Stability Function. An explicit analytical solution explaining the synchronization of SNAs is reported in the literature for the first time.
