Reduced-Order Active Vibration Control for High-Rise Buildings

For robust active vibration control for high-rise buildings, LQ control using a reduced-order model, spillover-considered control and spillover control using a low-pass filter are studied in this paper. In the numerical calculations, it is shown that the highest control performance is achieved by using a low-pass filter. In order to investigate the effectiveness of the present control methods, experiments using an 8-story model structure were carried out for the 4th-order reduced control. From the experiment results, the usefulness and feasibility of the control method for high-rise buildings are clarified.
