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

摘要

We discuss some issues related with the process of controlling space-time chaoticstates in the one dimensional Complex Ginzburg-Landau equation (CGLE). Weaddress the problem of gathering control over turbulent regimes with the only useof a limited number of controllers, each one of them implementing in parallel a localcontrol technique for restoring an unstable plane wave solution. We show that thesystem extension does not in uence the density of controllers needed in order to achieve control.
