本文提出了一种多自由度动力吸振器，它具有多个辅助质量，可以被动地抑制结构在地震作用下的多个振动模态。利用H∞静态输出反馈控制理论，通过求解双线性矩阵不等式（BMI）问题，确定了动力吸振器的可设计参数。最后，对两自由度动力吸振器进行了数值仿真，与传统的单自由度动力吸振器进行了比较，结果表明了该方法的优越性。
This paper proposes a multi-degree-of-freedom dynamic absorber, which has multiple auxiliary masses and can suppress multiple vibration modes of structures passively during earthquake. The designable parameters of the dynamic absorber are determined by utilizing a theory of H∞ static output feedback control and by solving a Bilinear-Matrix-Inequality (BMI) problem. Finally, numerical simulations for the two-degree-of-freedom dynamic absorber show the advantages of the proposed method compared with the conventional single-degree-of-freedom dynamic absorber.Copyright © 2004 by ASME
