result for a fluid-structure interaction problem. In dimension two,
a rigid structure moves into an incompressible fluid governed by
Navier-Stokes equations. The control acts on a fixed subset of the
fluid domain. We prove that, for small initial data, this system is

driven at rest and the structure to its reference configuration at
time T. To show this result, we first consider a linearized

Carleman inequality, we prove an optimal controllability result with
a regular control. Next, with the help of Kakutani's fixed point
theorem and a regularity result, we pass to the nonlinear problem.

AB - In this paper, we prove a controllability
result for a fluid-structure interaction problem. In dimension two,
a rigid structure moves into an incompressible fluid governed by
Navier-Stokes equations. The control acts on a fixed subset of the
fluid domain. We prove that, for small initial data, this system is
null controllable, that is, for a given T > 0, the system can be
driven at rest and the structure to its reference configuration at
time T. To show this result, we first consider a linearized
system. Thanks to an observability inequality obtained from a
Carleman inequality, we prove an optimal controllability result with
a regular control. Next, with the help of Kakutani's fixed point
theorem and a regularity result, we pass to the nonlinear problem.
