This paper describes an approach for suppressing earthquake-induced vibrations of building structures. The design of the control system is based on the equivalent-input-disturbance approach for improving the vibration rejection performance. A control system configuration with a vibration estimator is described, and a method of designing such a control system that employs Η∞ control is presented. The vibration rejection performance is guaranteed by the control structure, in which an equivalent vibration signal on the control input channel is estimated and directly incorporated into the control input. The validity of our method is demonstrated through simulations.
