结构主动质量阻尼器控制系统的μ综合分析

μ Synthesis for Active Mass Damper Control System of Structures

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 this paper structure stiffness uncertainty and earthquake excitation are considered in active mass damper(AMD) control system. Based on μ synthesis and H ∞ designed techniques, the close loop is designed to mitigate the vibration of structure and guarantee robustness for the variation of structure stiffness. μ synthesis is applied by using the D K iteration scheme. In order to apply this algorithm toilsome changes must be taken. The uncertainty modeling and robust perfomance design are shown for a 5 story building structure control system.
