Active Vibration Control of a Plate Type Element

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 creation of a structurally simple, cheap and easily replaceable active control systems for metal panels is discussed. The final future aim is to control and to reduce noise, produced by vibrations of metal panels of the body of a car. The paper is focused on a preliminary study, in controlled laboratory conditions, on a simple test article, represented by a rectangular aluminum plate, to compare performances of two possible control approach: Synchronized Shunted Switch Architecture (SSSA) and a feed-forward control.
