Phys. Rev. E 69, 056202 (2004) [4 pages]Spatiotemporal chaos control with a target wave in the complex Ginzburg-Landau equation systemReceived 31 October 2003; published 11 May 2004 An effective method for controlling spiral turbulence in spatially extended systems is realized by introducing a spatially localized inhomogeneity into a two-dimensional system described by the complex Ginzburg-Landau equation. Our numerical simulations show that with the introduction of the inhomogeneity, a target wave can be produced, which will sweep all spiral defects out of the boundary of the system. The effects exist in certain parameter regions where the spiral waves are absolutely unstable. A theoretical explanation is given to reveal the underlying mechanism. © 2004 The American Physical Society URL:
