Abstract

The paper describes in progress research activities aimed at verifying the possibility of designing active vibration control systems based on piezoelectric devices. In particular a wholly clamped rectangular flat panel is mechanically excited and controlled with piezoceramic patches. Vibrations reduction tests and then correlations with numerical predictions, based on an integrated piezo- structural model, are presented. In this work only simple co-located direct feed- back laws have been used to point out problems related to measurement conditioning circuits. Self sensing actuators have been also tested, the theoretical possibilities offered by this kind of devices being evident, but their actu
