Successful implementation of an active vibration control system is strictly correlated to the exact knowledge of the dynamic behavior of the the system, of the excitation level and spectra and of the sensor and actuator’s specification. Only the correct management of these aspects may guarantee the correct choice of the control strategy and the relative performance. Within this paper, some preliminary activities aimed at the numerical and experimental dynamic characterization of a plate type test article as well as the evaluation of piezoelectric sensors and actuators will be presented and discussed. All these information represent, in-fact, the basic information for a successive choice and implementation of the more appropriate active control strategy
