中文摘要:

我们调查了被外部噪音仅仅导致的二个联合电气化学的振荡器的合作动力学的反馈控制。交往电气化学的房间与没有自治摆动在发生的参数价值被建模,并且每个单位被它随机的变化的自己的来源强迫。推迟的反馈到的申请仅仅,二个分系统之一被显示能在给定的分系统或全球性改变导致噪音的摆动的连贯和时间规模。它能也在某些条件下面导致或压制随机的回声。

英文摘要:

We have investigated the feedback control of the cooperative dynamics of two coupled electrochemical oscillators that is induced merely by external noise. The interacting electrochemical cells are modeled with parameter values at which no autonomous oscillations occur, and each unit is forced by its own source of random fluctuations. Application of delayed feedback to only one of two subsystems is shown to be able to change the coherence and time scales of noise-induced oscillations either in the given subsystem or globally. It can also induce or suppress stochastic resonance under the certain conditions.
