Delayed feedback as a means of control of noise-induced motion
preprint
posted on 2005-07-22, 11:39 authored by Natalia JansonNatalia Janson, Alexander BalanovAlexander Balanov, E. SchollTime–delayed feedback is exploited for controlling noise–induced motion in coherence resonance
oscillators. Namely, under the proper choice of time delay, one can either increase or decrease
the regularity of motion. It is shown that in an excitable system, delayed feedback can stabilize
the frequency of oscillations against variation of noise strength. Also, for fixed noise intensity, the
phenomenon of entrainment of the basic oscillation period by the delayed feedback occurs. This
allows one to steer the timescales of noise-induced motion by changing the time delay.
