Improvement of time-delayed feedback control by oscillating feedback — •Andreas Fichtner1, Andreas Fichtner1, Wolfram Just2, Günter Radons1, and Wolfram Just2 — 1Institute of Physics, Chemnitz University of Technology, Chemnitz, Germany — 2Department of Mathematics, Queen Mary/University of London, London, UK
By imposing time dependent modulation on the control amplitude the performance of time-delayed feedback control may be enhanced. The relative phase between the control loop and the target state plays the crucial role. We investigate these features by analytical methods in a simple time discrete model. The linear stability analysis clearly shows the dependence of the control properties on the relative phase of the periodic orbit.
