This research consists of mainly following two parts of which results are as follows :In order to use Active Mass Dampers (AMD) for the seismic response control of structures, excessive auxiliary mass displacements must be avoided even under a high level of excitation, which becomes a critical factor in the event of strong earthquakes. The control algorithm for the full-scale multi-story steel frame test structure at DPRI, Kyoto University takes advantage of a nonlinear control scheme based on a variable gain method to overcome this difficulty. The nonlinear control scheme based on a variable gain method to overcome this difficulty. The nonlinear control used in the test achieves effective use of AMD with a limited displacement range of the auxiliary mass for structures under various levels of seismic input. The structural control test is conducted to verify the efficiency of the variable gain control scheme when used with the full-scale test structures. The test result using a seismic record shows the effectiveness of the control method, especially when subjected to a strong earthquake excitation.Control methods for seismic response reduction using an actuator installed between two buildings are investigated. Simultaneous control of two structures is possibly more difficult than controlling a single building. In this research, response of two real buildings consisted of 3-story and 5-story connected by an actuator is studied by numerical simulation and experiments. Two robust control theories are applied to the numerical calculation. The one is the H-infinity norm optimal control theory which is essentially a frequency domain design, and the other is the Sliding mode control theory, which is a design method in the time domain, Application of these theories proves to effectively reduce the seismic response.

本研究主要由两部分组成，主要研究结果如下：为了将主动质量阻尼器(AMD)用于结构的地震反应控制，即使在高水平的激励下也必须避免过大的辅助质量位移，这是发生强震时的一个关键因素。京都大学DPRI的足尺多层钢框架试验结构的控制算法利用了一种基于变增益方法的非线性控制方案来克服这一困难。为了克服这一困难，提出了基于变增益方法的非线性控制方案。试验中采用的非线性控制实现了AMD的有效利用，在不同水平的地震输入下，结构的辅助质量的位移范围有限。进行了结构控制试验，以验证变增益控制方案在全尺寸试验结构中的有效性。利用地震记录进行的试验结果表明，该控制方法是有效的，特别是在强震激励下。研究了安装在两个建筑物之间的致动器的减震控制方法。同时控制两个结构可能比控制单个建筑更困难。本文通过数值模拟和实验相结合的方法，对两栋由执行器连接的三层和五层实际建筑的响应进行了研究。在数值计算中应用了两种鲁棒控制理论。一种是H-无穷范数最优控制理论，本质上是一种频域设计；另一种是滑模控制理论，这是一种在时间域上的设计方法，应用这些理论可以有效地减小地震反应。
