Abstract  In this paper, we consider the Timoshenko equation of a nonuniform beam,with clamped boundary condition at one end and with feedback controls at the other end. It is proved that the system is backward wellposedness when the feedback controls are weak enough.

Key words： backward wellposedness      nonuniform beam      Timoshenko equation      c0-semigroup
