动力系统的同步:一种使用计算机代数系统的方法

Synchronization of dynamical systems: an approach using a Computer Algebra System

Guillermo Dávila, Antonio Morante, José A Vallejo

摘要:

两个动力系统之间的同步是自然界中最吸引人的现象之一。惠更斯在两个摆的情况下已经观察到,它是混沌系统的当前研究领域,在物理学,生物学或工程学中有许多应用。我们提出了一个基本的,但详细的探索这一现象背后的理论,包括一些图形动画,在免费的CAS Maxima的帮助下,但代码可以很容易地移植到其他CAS。使用的例子是洛伦兹吸引子和一对耦合摆,因为这些都是众所周知的动力系统模型,但程序适用于任何系统描述的一阶微分方程系统。

英文摘要:

The synchronization between two dynamical systems is one of the most appealing phenomena occurring in Nature. Already observed by Huygens in the case of two pendula, it is a current area of research in the case of chaotic systems, with numerous applications in Physics, Biology or Engineering. We present an elementary but detailed exploration of the theory behind this phenomenon, including some graphical animations, with the aid of the free CAS Maxima, but the code can be easily ported to other CASs. The examples used are the Lorentz attractor and a pair of coupled pendula because these are well-known models of dynamical systems, but the procedures are applicable to any system described by a system of first-order differential equations.
