Laboratory model for active vibration control

This paper describes a laboratory model for experiments with an active vibration control. This test rig is consisting of steel cantilever beam connected to aluminium frame in vertical position; stack piezoactuator fixed near clamped end of the cantilever beam and a piezoelectric accelerometer positioned at the free end of the beam. Control algorithm is implemented into digital signal processing system. Experiments with suppression of several vibration modes were performed on this laboratory model.
