paper deals with the stabilization problem for the Korteweg-de Vries
equation posed on a bounded interval. The control acts on the left
Dirichlet boundary condition. At the right end-point, Dirichlet and
Neumann homogeneous boundary conditions are considered. The proposed
feedback law forces the exponential decay of the system under a
smallness condition on the initial data. Moreover, the decay rate can
be tuned to be as large as desired. The feedback control law is
designed by using the backstepping method.
