Experimental control of chaos in a delayed high-dimensional system

We introduce a novel control method for a delayed dynamical system exhibiti ng high-dimensional chaos. The control is based on a negative feedback loop with an adaptive filtering, consisting of a selective filter, centered at the frequency of the orbit to be stabilized, with the addition of a time de rivative correction. The validity of the method is also discussed in the fr amework of a space-like representation adopted to study the analogies betwe en delayed dynamical systems and spatially extended systems.
