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.
