利用流形方程构造广义同步流形

Constructing Generalized Synchronization Manifolds by Manifold Equation

Jie Sun, Erik M. Bollt, Takashi Nishikawa

摘要:

完全理解耦合动力系统的同步行为超出了相同的情况下,需要显式的广义同步流形的建设,无论我们希望比较系统,或了解他们的稳定性。尽管如此,虽然同步已经成为一个非常热门的话题,但这一领域的大部分研究都集中在相同的情况下,特别是因为它的不变流形只是恒等函数,并且还没有任何普遍可行的方法来计算非相同系统的广义同步流形。在这里,我们推导出时间相关的偏微分方程,其稳态解正好反映了广义同步流形,尊重其稳定性。我们引入了一种新的方法来处理微妙的问题,边界条件的数值方案来解决偏微分方程,我们开发的一阶扩展接近相同的情况。我们给出了几个日益复杂的例子,包括耦合不相同的范德波尔振荡器。利用流形方程,我们还讨论了耦合器的设计,以达到预期的同步。

英文摘要:

Full understanding of synchronous behavior in coupled dynamical systems beyond the identical case requires an explicit construction of the generalized synchronization manifold, whether we wish to compare the systems, or to understand their stability. Nonetheless, while synchronization has become an extremely popular topic, the bulk of the research in this area has been focused on the identical case, specifically because its invariant manifold is simply the identity function, and there have yet to be any generally workable methods to compute the generalized synchronization manifolds for non-identical systems. Here, we derive time dependent PDEs whose stationary solution mirrors exactly the generalized synchronization manifold, respecting its stability. We introduce a novel method for dealing with subtle issues with boundary conditions in the numerical scheme to solve the PDE, and we develop first order expansions close to the identical case. We give several examples of increasing sophistication, including coupled non-identical Van der Pol oscillators. By using the manifold equation, we also discuss the design of coupling to achieve desired synchronization.
