本文对建筑结构主动反应控制系统可靠性评估的研究进行了总结。第一章绪论。第二章建筑结构响应控制系统的发展现状。第三章CTAC测试仪的研制。第四章利用CTAC的实验研究和数值模拟对各种主动控制算法的可靠性进行评估。第五章先进的主动控制系统。第六章结语。第三章中的CTAC(主动响应控制紧凑型测试系统)是在大阪大学开发的，它对各种主动控制系统的测试显示了很高的性能。在第四章中，研究了多种不同的控制算法。提出了一种实用的新型控制算法--“数字最优控制”算法。使用此算法时，不会发生溢出。作为先进的主动控制系统，第五章介绍了两种新型的主动控制概念：主动鳍控制系统和主动耦合控制系统。风洞对主动减摇鳍有效转角的研究起着重要的作用。用一组弹簧和电机实现的虚拟负刚度在“两结构主动耦合控制”中取得了较好的效果。

This report a summary of researches regarding to evaluations of reliability of active response control systems of building structures. The contents are composed by following chapters.Chapter 1.Introduction.Chapter 2.The state-of-the-art of response control systems for building structures.Chapter 3.Development of a testing apparatus CTAC.Chapter 4.Evaluation of reliabilities for various active control algorithms by experimental investigations using CTAC and by numerical simulations.Chapter 5.Advanced active control system.Chapter 6.Concluding remarks.The CTAC (Compact Testing system for Active response Control) in Chapter 3 was developed in Osaka university, and it shows high performances for testing various kinds of active control systems. In Chapter 4, many different kinds of control algorithms are examined. And a practical new control algorithm named 'Digital-Optimizing Control' algorithm is proposed. With this algorithm, no spill over has been occurred. As advanced active control systems, in Chapter 5, two new types of active control concepts 'Active fin control system' and 'Active coupling control system' are introduced. Wind tunnel plays important roll to investigate the effective angle of the rotatable fin in the 'Active fin control'. And, virtual negative stiffness which can be realized by a set of spring and motor makes good results in the 'Active coupling control of two structures'.
