Since elastic vibration of railway vehicle deteriorates the riding comfort of passengers, it is an important problem for a lightweight high speed railway vehicle to reduce such vibration. A finite element method (FEM) model of lightweight vehicle is designed, which is composed by body and bogies, and its modal analysis is performed. And it is devised how to reduce the first vertical bending vibration by the control system which is designed based on the analytical result. This study adopts an active dynamic absorber installed under the body floor, which is designed by taking into account only the vertical direction vibration. The controller with high robustness is designed by applying the H_∞lμ control method in consideration of parameter variations and model errors in uncontrolled modes simultaneously.
