Query: Output feedback stabilization of the Korteweg-de Vries equation *   This paper presents an output feedback control law for the Korteweg-de Vries
equation. The control design is based on the backstepping method and the
introduction of an appropriate observer. The local exponential stability of the
closed-loop system is proven. Some numerical simulations are shown to
illustrate this theoretical result.
