| Abstract. This paper deals with a control problem of a Cauchy System for an hyperbolic operator.The associate system here which is distributed and singular has in general no solution, and when a solution does exist it is unstable. So instead of considering the control v and the state z separately, we consider the pair control-state (v, z); it suffices then to make sure that the set of admissible pairs (v, z) is non-empty. We establish the existence and the uniqueness of the optimal pair and then we characterize it by using the penalization method. | |
