时滞系统中的混沌

Chaos in time delay systems, an educational review

Hendrik Wernecke, Bulcsú Sándor, Claudius Gros

摘要:

在物理世界中交换信息所需的时间在相应的系统由微分方程建模时引起延迟项。因此,时间延迟是普遍存在的,而且很可能引起不稳定性,并与它的各种混沌相。那么,哪些是可能的类型的时间延迟,诱导的混沌状态,和方法适合于表征所产生的动态?这篇评论提出了一个概述的领域,包括深入讨论的最重要的结果,标准的数值方法和几个新的测试识别混沌。特别强调的是放在一个结构化的表示,是直接遵循。几个教育的例子也包括在内,另外作为切入点,迅速发展的领域的时间延迟系统。

英文摘要:

The time needed to exchange information in the physical world induces a delay term when the respective system is modeled by differential equations. Time delays are hence ubiquitous, being furthermore likely to induce instabilities and with it various kinds of chaotic phases. Which are then the possible types of time delays, induced chaotic states, and methods suitable to characterize the resulting dynamics? This review presents an overview of the field that includes an in-depth discussion of the most important results, of the standard numerical approaches and of several novel tests for identifying chaos. Special emphasis is placed on a structured representation that is straightforward to follow. Several educational examples are included in addition as entry points to the rapidly developing field of time delay systems.
