In this study, an active vibration absorber (DVA) driven by an AC servomotor through a ball screw was developed, the facilities of which are smaller than the usual one controlled by a servo hydraulic actuator. The optimization of the controller is performed taking account of the dynamic characteristics of the active DVA driven by a velocity control driver. By carrying out digital-computer-controlled-type tests and numerical calculations using a 4-story, 11-ton frame model structure, it is demonstrated that the adtive DVA (absorber's mass ratio to the structure is only 0.5%) can reduce the response of every story, not only the displacement but also the acceleration, to 1/3 compared with uncontrolled ones. The usefulness and feasibility of the present active DVA for high-rise buildings are clarified.
