Popis: The control of a linear dispersive system coupling a Schrodinger and a linear Korteweg–de Vries equation is studied in this paper. The system can be viewed as three coupled real-valued equations by taking real and imaginary parts in the Schrodinger equation. The internal null controllability is proven by using either one complex-valued control on the Schrodinger equation or two real-valued controls, one on each equation. Notice that the single Schrodinger equation is not known to be controllable with a real-valued control. The standard duality method is used to reduce the controllability property to an observability inequality, which is obtained by means of a Carleman estimates approach.
