This paper presents a study of low frequency volume velocity vibration control ofa smart panel in order to reduce sound transmission. A distributed piezoelectricquadratically shaped polyvinylidene fluoride (PVDF) polymer film is used as auniform force actuator and a 4 × 4 accelerometer array is used as a volumevelocity sensor for the implementation of a single-input single-outputcontrol system. The theoretical and experimental study of sensor–actuatorfrequency response function shows that this sensor–actuator arrangementprovides a required strictly positive real frequency response function belowabout 900 Hz. Direct velocity feedback could therefore be implementedwith a limited gain which gives reductions of about 15 dB in vibrationlevel and about 8 dB in acoustic power level at the (1, 1) mode of thesmart panel. It has been also shown that the shaping error of the PVDFactuator could limit the stability and performance of the control system.
