异步离散动力系统

Asynchronous discrete dynamical systems

Stefan Siegmund, Petr Stehlik

摘要:

研究了两个具有不同(异步)周期时间尺度的耦合离散时间方程。耦合是采样保持类型的,即,每个方程的状态在其更新时间被采样并保持,直到它在另一个方程的下一个更新时间被读取为输入。在两个时间尺度的并集上构造了一个插值的二维复值系统,在两个时间尺度的交集上构造了一个外推的四维复值系统。我们讨论了稳定性的几个结果,例子和反例在不同的框架,以显示的稳定性可以有显着的影响的动力学性质。

英文摘要:

We study two coupled discrete-time equations with different (asynchronous) periodic time scales. The coupling is of the type sample and hold, i.e., the state of each equation is sampled at its update times and held until it is read as an input at the next update time for the other equation. We construct an interpolating two-dimensional complex-valued system on the union of the two time scales and an extrapolating four-dimensional system on the intersection of the two time scales. We discuss stability by several results, examples and counterexamples in various frameworks to show that the asynchronicity can have a significant impact on the dynamical properties.
