Interior Controllability of a Timoshenko Type Equation

In this paper we prove the interior controllability of the following Timoshenko Type Equation where is a sufficiently regular bounded domined in and such that ,ω is an open nonempty subset of , 1ω denotes the characteristicfunction of the set ω and the distributed control . Specifically, we prove the following statement: For all the system is approximatelycontrollable on . Moreover, we exhibit a sequence of controls steering thesystem from an initial state to a final state in a prefixed time.
