Controlling Spatio-temporal chaos in the scenario of the one-dimensional complex Ginzburg-Landau equation

We discuss some issues related with the process of controlling space –time chaotic states in the one-dimensional complex Ginzburg –Landau equation.We address the problem of gathering control over turbulent regimes with the use of only a limited number of controllers,each one of them implementing,in parallel,a local control technique for restoring an unstable plane-wave solution.We show that the system extension does not influence the density of controllers needed in order to achieve control.
