Delayed feedback control of chaos

K Pyragas - … Transactions of the Royal Society A …, 2006 - royalsocietypublishing.org
Time-delayed feedback control is well known as a practical method for stabilizing unstable
periodic orbits embedded in chaotic attractors. The method is based on applying feedback …

Chaos in time delay systems, an educational review

H Wernecke, B Sándor, C Gros - Physics Reports, 2019 - Elsevier
The time needed to exchange information in the physical world induces a delay term when
the respective system is modeled by differential equations. Time delays are hence …

Delayed feedback as a means of control of noise-induced motion

NB Janson, AG Balanov, E Schöll - Physical review letters, 2004 - APS
Time-delayed feedback is exploited for controlling noise-induced motion in coherence
resonance oscillators. Namely, under the proper choice of time delay, one can either …

Refuting the odd-number limitation of time-delayed feedback control

B Fiedler, V Flunkert, M Georgi, P Hövel, E Schöll - Physical Review Letters, 2007 - APS
We refute an often invoked theorem which claims that a periodic orbit with an odd number of
real Floquet multipliers greater than unity can never be stabilized by time-delayed feedback …

Control based bifurcation analysis for experiments

J Sieber, B Krauskopf - Nonlinear Dynamics, 2008 - Springer
We introduce a method for tracking nonlinear oscillations and their bifurcations in nonlinear
dynamical systems. Our method does not require a mathematical model of the dynamical …

Delayed feedback control of chaos: Bifurcation analysis

AG Balanov, NB Janson, E Schöll - … Review E—Statistical, Nonlinear, and Soft …, 2005 - APS
We study the effect of time delayed feedback control in the form proposed by Pyragas on
deterministic chaos in the Rössler system. We reveal the general bifurcation diagram in the …

Control of unstable steady states by long delay feedback

S Yanchuk, M Wolfrum, P Hövel, E Schöll - Physical Review E—Statistical …, 2006 - APS
We present an asymptotic analysis of time-delayed feedback control of steady states for
large delay time. By scaling arguments, and a detailed comparison with exact solutions, we …

Control of noise-induced oscillations by delayed feedback

AG Balanov, NB Janson, E Schöll - Physica D: Nonlinear Phenomena, 2004 - Elsevier
We propose a method to control noise-induced motion, based on using delayed feedback in
the form of the difference between the delayed and the current states of the system. The …

Beyond the odd number limitation: A bifurcation analysis of time-delayed feedback control

W Just, B Fiedler, M Georgi, V Flunkert, P Hövel… - Physical Review E …, 2007 - APS
We investigate the normal form of a subcritical Hopf bifurcation subjected to time-delayed
feedback control. Bifurcation diagrams which cover time-dependent states as well are …

Noise-induced cooperative dynamics and its control in coupled neuron models

B Hauschildt, NB Janson, A Balanov, E Schöll - Physical Review E—Statistical …, 2006 - APS
We investigate feedback control of the cooperative dynamics of two coupled neural
oscillators that is induced merely by external noise. The interacting neurons are modeled as …
