In order to realize a system that reduces multi-modes of floor vibration and accompanying structure-borne sound by a single sensor and an actuator per unit span area, a method of active vibration control and a procedure to identify the control object are described. Then the good performance of the method and procedure is demonstrated with numerical simulations. Their usefulness has also been shown through experiments with a life-size floor structure. It is verified that the first three modes of vibration and structure-borne sound are reduced as designed by about 10dB at the first mode and some 5dB at the second and third modes. The method and procedure will lead to the active control system with automatic control design function for floor vibration and structure-borne sound.
