External feedback control of chaos using approximate periodic orbits.
We apply the external feedback technique to control chaos in real physical systems. The target, unstable periodic orbits embedded in chaotic attractors are obtained from chaotic time series in terms of the delay coordinates technique. We demonstrate its efficiency for periodically forced, single- and two-degree-of-freedom systems consisting of one or two pendula in numerical simulations and experiments.
