Active Control of Sound Radiation into an Enclosure using Different Number of Actuators
This paper presents an investigation into the active control of structural-acoustic coupled system of a rectangular enclosure involving two simply supported flexible plates.One of the two plates is driven by a point force.The locations of actuators are determined by considering contour plot of the optimal potential energy.The control mechanisms for this enclosure are analyzed when one,two and three actuators are applied on one of the plates.Results obtained demonstrate that the control mechanisms for Panel a are always modal restructuring; those for Panel b are dominantly modal suppression when a different number of actuators is applied to reduce the noise level.
