在结构主动质量阻尼器（ＡｃｔｉｖｅＭａｓｓＤａｍｐｅｒ——ＡＭＤ）控制系统中考虑结构刚度的变异和地震激励作用，根据μ综合分析和Ｈ∞设计原理，设计闭环控制系统使其既可以抑制在地震作用下的结构振动，又使结构刚度在有界范围内变化时保持闭环系统的稳定。在本文中μ综合设计方法为Ｄ－Ｋ循环。为了利用Ｄ－Ｋ循环技术，对开环系统进行了必要的改造，最后文中给出了一个五层ＡＭＤ结构控制系统的分析、设计与数值仿真的结果。
In the active mass damper (ActiveMassDamper-AMD) control system, the structural stiffness variation and seismic excitation are considered. Based on μ synthesis analysis and H∞ design principles, a closed-loop control system is designed to suppress the structure under earthquake action. Vibration, in turn, maintains the stability of the closed-loop system when the structural stiffness changes within a bounded range. In this paper, the μ-integrated design method is a D-K cycle. In order to utilize the D-K cycle technology, the necessary reformation of the open-loop system is carried out. Finally, the analysis, design and numerical simulation results of a five-layer AMD structure control system are given.
