Olga I. Moskalenko, Alexander E. Hramov, Alexey A. Koronovskii, Alexey A. Ovchinnikov

摘要:

研究了噪声对耗散耦合混沌系统广义同步的影响。如果驱动系统和响应系统的吸引子具有无穷大的吸引域,则广义同步具有很大的稳定性。揭示的特殊性的原因是通过修改的系统方法[A.E. Hramov,A.A. Koronovskii,Phys. Rev. E. 71,067201(2005)],并通过数值计算和实验研究的结果证实。主要结果用单向耦合混沌振子和离散映射以及空间扩展动力系统的例子来说明。分析了不同类型的模型噪声。揭示的特殊性可能的应用进行了简要讨论。

英文摘要:

The influence of noise on the generalized synchronization regime in the chaotic systems with dissipative coupling is considered. If attractors of the drive and response systems have an infinitely large basin of attraction, generalized synchronization is shown to possess a great stability with respect to noise. The reasons of the revealed particularity are explained by means of the modified system approach [A.E. Hramov, A.A. Koronovskii, Phys. Rev. E. 71, 067201 (2005)] and confirmed by the results of numerical calculations and experimental studies. The main results are illustrated using the examples of unidirectionally coupled chaotic oscillators and discrete maps as well as spatially extended dynamical systems. Different types of the model noise are analyzed. Possible applications of the revealed particularity are briefly discussed.
