✦ Synopsis

The spatio-temporal chaos in the system described by a one-dimensional nonlinear-drift wave equation is controlled by directly adding a periodic force with appropriately chosen frequencies. By dividing the solution of the system into a carrier steady wave and its perturbation, we find that the controlling mechanism can be explained by a slaving principle. The critical controlling time for a perturbation mode increases exponentially with its wave number.

The work deals with control of spatio-temporal chaos in coupled ordinary differential equations. We propose a method based on the following ideas: stabilization of unstable periodic orbits embedded in spatio-temporal chaos, perturbation of minimal number of system variables, and perturbation only at
