Abstract
This paper is concerned with a design method f multi-degree-of-freedom dynamic absorbers which can suppress multiple vibration modes passively. Design parameters of the dynamic absorber are determined by utilizing the theory of the H∞ static output feedback control theories and by solving Bilinear-Matrix-Inequality (BMI) problem. Finally, numerical simulations for the two-DOF dynamic absorber show the advantages of the proposed design compared with the conventional SDOF dynamic absorbers.
