We consider a distributed system in which the state is governed by a parabolic equation and a pair of controls where and play two different roles: the control is of type while expresses that the state does not move from a given state. Therefore, it is natural to introduce the control point of view. In fact, there are several ways to state and solve optimal control problems with a pair of controls and , in particular the method with only one criteria for the pair or...

Exact controllability to trajectories for semilinear heat equations with discontinuous diffusion coefficients

Anna Doubova, A. Osses, J.-P. Puel (2002)

ESAIM: Control, Optimisation and Calculus of Variations

Similarity:

The results of this paper concern exact controllability to the trajectories for a coupled system of semilinear heat equations. We have transmission conditions on the interface and Dirichlet boundary conditions at the external part of the boundary so that the system can be viewed as a single equation with discontinuous coefficients in the principal part. Exact controllability to the trajectories is proved when we consider distributed controls supported in the part of the domain where...
