Control of spatiotemporal disorder in parametrically excited surface waves

The parametrically excited surface waves were investigated to study the control of spatiotemporal disorder. The study described nonlinear waves on the 2D surface of a fluid, and the uncontrolled system was driven by a spatially uniform, temporally periodic vibration of the fluid layer. By imposing a small-amplitude control frequency, both the control of the state and force rapid transitions between different, stabilized, nonlinear states was achieved. It was observed that the mechanism driving the spatiotemporal disorder in the system is the continual competition between a number of specific nonlinear states.
