Controlling spatiotemporal chaos using multiple delays

Phys Rev E Stat Nonlin Soft Matter Phys. 2007 Jun;75(6 Pt 2):065202. doi: 10.1103/PhysRevE.75.065202. Epub 2007 Jun 21.

Abstract

A control method for manipulating spatiotemporal chaos is presented using lumped local feedback with several different delay times. As illustrated with the two-dimensional Ginzburg-Landau and the Fitzhugh-Nagumo equation this method can, for example, be used to convert chaotic spiral waves into guided plane waves and for trapping spiral waves.
