慢-快系统中的延迟诱导开关态

Delay-Induced Switched States in a slow-fast system

Stefan Ruschel, Serhiy Yanchuk

摘要:

研究了具有小参数$\varepsilon,η$和正反馈函数$f$的二分量时滞系统$\varepsilon x^{\prime}(t)=-x(t)-y(t)+f(x(t-1)),$ $y^{\prime}(t)=ηx(t)$.以前,这样的系统已经被报道在光电实验中模拟切换,其中每个切换在大约一个延迟时间之后引起另一个切换,该延迟时间与信号的一个往返有关。在本文中,我们研究这些延迟诱导的切换状态。我们提供了它们存在的条件,并显示如何正式的限制$\varepsilon\to0$和/或$η\to0$促进我们对这种现象的理解。

英文摘要:

We consider the two-component delay system $\varepsilon x^{\prime}(t)=-x(t)-y(t)+f(x(t-1)),$ $y^{\prime}(t)=ηx(t)$ with small parameters $\varepsilon,η$, and positive feedback function $f$. Previously, such systems have been reported to model switching in optoelectronic experiments, where each switching induces another one after approximately one delay time, related to one round trip of the signal. In this paper, we study these delay-induced switched states. We provide conditions for their existence and show how the formal limits $\varepsilon\to0$ and/or $η\to0$ facilitate our understanding of this phenomenon.
