Active suspensions have been considered for improving the ride quality of railway vehicles. Recently various control methods have been proposed. In this paper preview control is studied. Preview control, a kind of feedforward control, has two disadvantages. ( 1 ) Preview control does not increase the stability of a system. ( 2 ) Safety problem occurs from the practical point of view when it fails. In order to compensate the above disadvantages, a combination control by preview and H_∞ feedback is considered in this paper. Numerical simulations are performed for lateral vibration of railway vehicles. It is shown that preview control reduces the vibration with small control power and that H2 control (feedback control) reduces residual vibration even if errors exist in preview information. Furthermore, the effect of this control system is confirmed by experiments.
