In the previous paper the authors proposed a new vibration control device (V.C.D.) using power generator. The device has an inertial force created inertia disk, and damping force derived an energy dissipation of the power generator. The trial experimental model was made, and the vibration tests were carried out in our laboratory. In this paper, for the purpose of applying the device to a real large structure, new two V.C.D.s for 15 kN range are manufactured, and shipped to NCREE, Taiwan. In order to investigate about dynamic properties of the V.C.D., performance tests are carried out, and the resisting force characteristics are measured. Next, vibration tests of 3-story structure when the V.C.D.s are attached are carried out using by shaking table. Seismic responses at each story are measured when the earthquake wave of Imperial Valley El Centro NS component is inputted. The control law based on minimizing the Lyapunov function is used, and it is controlled by Bang-Bang type. The effects of vibration suppression using the V.C.D. are confirmed.
