混沌振子的相位描述

Phase description of chaotic oscillators

Takashi Imai, Hiromichi Suetani, Toshio Aoyagi

摘要:

本文提出了一种混沌动力学的相位描述方法,用于混沌相位同步的研究。所提出的描述的一个突出特点是,它系统地结合了系统中固有的非相变量的动态。考虑到这些非相位动力学是必不可少的捕捉混沌相位同步的复杂性质,即使在定性的方式。我们数值验证了所提出的描述的有效性,在应用到Rössler和Lorenz振荡器,我们发现,我们的方法提供了一个准确的描述这些混沌振荡器的同步区域的特征扭曲的形状。此外,所提出的描述使我们能够系统地识别和描述这种扭曲的起源。

英文摘要:

This paper presents a phase description of chaotic dynamics for the study of chaotic phase synchronization. A prominent feature of the proposed description is that it systematically incorporates the dynamics of the non-phase variables inherent in the system. Taking these non-phase dynamics into account is essential for capturing the complicated nature of chaotic phase synchronization, even in a qualitative manner. We numerically verified the validity of the proposed description in application to the Rössler and Lorenz oscillators, and we found that our method provides an accurate description of the characteristic distorted shapes of the synchronization regions for these chaotic oscillators. Furthermore, the proposed description allows us to systematically identify and describe the origin of this distortion.
