Recently, the application of active suspension has been studied for improving the ride quality of railway vehicles. In active vibration control of railway vehicles, it is important that the control system be robust against parameter variations. In one such study, it was indicated that a LQG controller had low stability of the robustness to mass variation of the car body due to the varying number of passengers. In this paper, the H_∞ controllaw is adopted for a 3 d. o. f. half-vehicle model, and the improvement of control performance is investigated experimentally. As a result, it is shown that the addition of a bogie-related state variable to body-related ones provides better control performance. The control performance is improved further by shortening the sampling period. Moreover, it is also shown that the H_∞ controller is more robust against mass variation of the car body.
