Abstract:

It was proved by Linares and Ortega that the linearized Benjamin-Ono equation posed on a periodic domain $\mathbb {T}$ with a distributed control supported on an arbitrary subdomain is exactly controllable and exponentially stabilizable. The aim of this paper is to extend those results to the full Benjamin-Ono equation. A feedback law in the form of a localized damping is incorporated into the equation. A smoothing effect established with the aid of a propagation of regularity property is used to prove the semi-global stabilization in $L^2(\mathbb {T})$ of weak solutions obtained by the method of vanishing viscosity. The local well-posedness and the local exponential stability in $H^s(\mathbb {T})$ are also established for $s>1/2$ by using the contraction mapping theorem. Finally, the local exact controllability is derived in $H^s(\mathbb {T})$ for $s>1/2$ by combining the above feedback law with some open loop control.
