As one of the global research of smart board, vibration control system was developed to suppress the vibrations which harm the health of structure. CFRP board reinforced by stiffeners is a target structure. In combination with FBG optical fiber sensors, PZT sensors, PVDF sensors and laminated PZT actuators, all attached on the surface of structure, vibration control system was constructed. First of all, effect of rigidity change by stiffeners on vibration mode was investigated by FEM and experimental modal analysis. Then, based on these results, locations of sensors and actuators ard decided and distributed clustered control system was constructed. Finally, suppression effect by this system was verified.
