Abstract:The active control of structurally radiated sound requires in general a large number of error sensors on the vibrating structure. A simple control strategy, using only one error signal -the volume velocity of the structure-has recently been proposed. Such a strategy allows (i) to control all the structural modes that are monopole radiators at low frequencies (i.e., with a high radiation efficiency), (ii) to keep the control set-up simple (only one information is to be minimized). The volume velocity is measure… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
