abstract = { We study the local exponential stabilization of the 2D and 3D
Navier-Stokes equations in a bounded domain, around a given
steady-state flow, by means of a boundary control. We look for a
control so that the solution to the Navier-Stokes equations be a
strong solution. In the 3D case, such solutions may exist if the
Dirichlet control satisfies a compatibility condition with the
initial condition. In order to determine a feedback law satisfying
such a compatibility condition, we consider an extended system
coupling the Navier-Stokes equations with an equation satisfied by
the control on the boundary of the domain. We determine a linear
feedback law by solving a linear quadratic control problem for the
linearized extended system. We show that this feedback law also
stabilizes the nonlinear extended system.
