Abstract

Aftyer two short visits to Freie Universität Berlin, we set up the problem of stabiulization of unstable periodic orbits of ordinary differential equations via time-delayed feedback systems. This type of control is known as "Pragas Control" and it has an advantadge of being non-invasive. The recent results have the disavantadge of having major constrains in the Floquet multipliers. (AU)
