In this study, active control system of buildings for severe earthquakes are developed and seismic response control experiments using a full-scale structure and a structural model by using a shaking table were performed to verify the structural control systems.1)The methodologies for the identification of structural parameters and estimation of structural responses were studies. The subspace-based system identification method was introduced. To certify the identification results, seismic vibration experiments under real earthquake were performed. 2)The specimen stucture utilized for structural control experiments is a five-story steel frame built in the Uji Campus of Kyoto University. To realize seismic motions of the specimen structure as if under earthquake, the earthquake response generator system was developed by using two excitors installed on the 5th and 3rd floors. Vibration tests of the full-scale structure demonstrate the accuracy and validity of the earthquake response genera … More tor system. 3)Seismic control experiments of the specimen structure with a AMD (Active Mass Damper) were conducted by using control algorithms based on LQ/LQG control theory, the pole assignment method and the H^* control theory. The effectiveness of the designed controllers were illustrated through seismic vibration experiments of the full-scale specimen structure by using the earthquake response generator system. 4)Seismic control experiments using an structural model specimen with rwo AMDs were also performed by using a shaking table. The stability and robustness of control algorithms were verified. 5)To develop algorithms that can control the AMD within its stroke limitation is an important problem in order to apply the AMD system to seismic response control for severe earthquakes. The algorithms with variable control gain were developed. Experiments using the full-scale test structure and Shaking-table experiments using the structural model specimen were perfomed. It is emphasized that the structural control systems have a feasibility of controlling buildings even during severe earthquakes. Less

本研究开发了大震作用下建筑物的主动控制系统，并进行了足尺结构和结构模型的振动台地震反应控制试验，以验证结构控制系统的有效性。1）研究了结构参数识别和结构反应估计的方法。介绍了基于子空间的系统辨识方法。为了验证识别结果，进行了真实的地震作用下的地震振动试验。2)结构控制实验所用的试件结构是京都大学宇治校区的一个五层钢框架。为了实现试件结构的地震运动，就像在地震下一样，地震反应发生器系统是通过使用安装在第5层和第3层的两个激励器开发的。足尺结构的振动试验验证了地震反应谱的正确性和有效性 ...更多信息 tor系统3)采用基于LQ/LQG控制理论、极点配置法和H^* 控制理论的控制算法，对安装AMD（Active Mass Damper）的试件结构进行了地震控制试验。利用地震反应发生器系统对足尺试件结构进行了地震振动试验，验证了所设计控制器的有效性。4)利用振动台进行了结构模型试件的地震控制试验。验证了控制算法的稳定性和鲁棒性。5）为了将AMD系统应用于大震的地震反应控制，开发能将AMD控制在其行程限制内的算法是一个重要的问题。提出了变增益控制算法。进行了足尺试验结构试验和结构模型试件振动台试验。它强调，结构控制系统具有控制建筑物，即使在严重的地震的可行性。少
