Finite element techniques were used for the discretization of the continuous beam and from the corresponding state space representation, control gains were obtained by the pole allocation method for the appropriated modal control. The results obtained from numerical simulation show that control of the first three vibration modes is efficiently accomplished with a single input control.]]></p></abstract>
