The two-dimensional unsteady separated flow perpendicular to a flat plate is considered. The rolling-up of the separated shear layer is modeled by a pair of point vortices. A suction point located on the downstream side of the plate acts as an actuator. A nonlinear feedback controller able to confine the wake to a single vortex pair of constant circulation is derived in closed form.

Abstract
The two-dimensional unsteady separated flow perpendicular to a flat plate is considered. The rolling-up of the separated shear layer is modeled by a pair of point vortices. A suction point located on the downstream side of the plate acts as an actuator. A nonlinear feedback controller able to confine the wake to a single vortex pair of constant circulation is derived in closed form.File in questo prodotto:
