摘要：

Controlling spatiotemporal chaos in two-dimensional (2D) coupled Ginzburg-Landau oscillators is investigated. When the controllers are spatially fixed, a huge number of controllers are needed for successful chaos control. We suggest an itinerant control approach to randomly move the controllers in the space. This new method can reach high control efficiency, i.e., we can use a single controller to successfully drive violent spatiotemporal chaos to regular target states if the itinerant operations are fairly fast.
