Total Design for Structural Control

面对土木工程领域结构控制技术的迅速发展，建筑设计理念也在改变着传统的设计理念。然而，在现阶段，结构的主动控制仍处于发展阶段，因此不能保证在大地震时的安全。本研究的主要目的之一是建立一个智能控制系统，即使在大地震的情况下也能工作。为了做到这一点，两个系统被证明有其有前途的可能性：一种是基于变增益的主动质量阻尼器（AMD）与滞回阻尼器的混合控制系统，另一种是基于变摩擦阻尼器的半主动控制系统。提出了受控结构模型降阶的概念，并论证了基于此概念的控制系统设计的有效性。

Faced with the rapid development of structural control technologies in the field of civil engineering, building design philosophy has been changing its traditional concept. However, in the current stage, active control of structures is still under development and hence not for ensuring the safety during large earthquakes. One of the major purposes of this research is to construct an intelligent control system which can work even in case of large earthquake. To do this, two systems are demonstrated to have their promising possibilities : one is a hybrid control system combining variable gain-based active mass damper (AMD) with hysteretic damper and the other is a semi-active system utilizing variable friction damper.For the purpose of constructing an appropriate reduced model for controlled high-rise building structures, the concept of model reduction for a controlled structure is presented and the effectiveness of the control system design based on such a concept is demonstrated.
