In studies of active vibration control of railway vehicles, recently, the preview control which has been designed using the LQ theorem or the H_∞ control has attracted the attention. In this paper, a design method of the preview control action based on the H_∞ control theorem is derived, such that the designed control system provides the desired features of both the preview control and the H_∞ control. A simulation study is done for the vertical vibration problem using a half-vehicle model. As a result of the simulation study, it is shown that the preview control action has some properties as follows. (a) The frequency response gain of the acceleration of car body in higher frequency range is reduced. (b) The variation of the pitch angle of car body is reduced. (c) The robustness against the mass variation of car body is obtained.
