738 複数構造物の MR ダンパを用いたセミアクティブ制御  [in Japanese] Semi-active Vibration Control for Buildings Connected with Bridges Using MR Damper  [in Japanese]

At present there are no control devices that can be matched for both small and large earthquake of a high-rise building. In order to control vibration of such a building, the connected building control method and variable damping device for realizing the semi-active control system is used. The semi-active device is defined as a kind of passive device with variable properties changed by external maneuvers. A magnetorheological fluid damper as a variable damping device is used. This paper presents two methods for designing the semi active controller with Genetic Algorithm and LQ control theory. The simulation and experimental results demonstrate the availability and possibility of semi-active control.
