Increase of deceleration in high-speed and high-density train operation degrades riding comfort and frequently causes wheel skids. This requires an introduction of the control engineering to upgrade the control performance of brake systems on rolling stocks. We are now studying a control method for mechanical brakes that uses friction and pneumatic pressure, including non-linear elements as the basis of brake force. Furthermore, the system itself has certain “dead time”, which is not ignorable and makes controlling difficult. One of our targets is to develop a brake control device that can control deceleration in accordance with a decelerating pattern that optimizes riding comfort and prevents wheel skids. In this paper, a design method of the controller for the deceleration tracking control and the system compensating the dead time are proposed. Finally, the effects of them are confirmed through computer simulations and experimental results.
