Three control methods for time -- dependent Fluid Flow

We summarize some of the recent developments in the field of optimal and suboptimal control strategies for time dependent incompressible Navier-Stokes equations. Besides the Newton method, reduced order modeling (ROM) and receding horizon control strategies are described. All approaches are applied to compute controls for the unsteady flow around a cylinder in two spatial dimensions.
