This paper deals with active boundary control termed ABC of a thin plate for the purpose of creating a completely vibration-free state ; a quiet zone, on the designated area of a target structure. First, the principle of ABC once developed for a one-dimensional structure is expanded to a two-dimensional structure, thereby enabling the generation of a quiet zone on the desired location of a structure. Then, using a transfer matrix method, an ABC system is described, fundamental properties of the system being investigated. Furthermore, in addition to conventional boundary conditions, two more boundary conditions are found to be created using ABC. Moreover, it is found that ABC has the capability of producing a completely vibration-free state on the designated area. Finally, in an effort to verify the validity of ABC presented in the work, a numerical analysis is conducted, demonstrating the capability of ABC using a simply supported panel.
