Increased deceleration in high-speed and high-density train operation worsens riding comfort and frequently causes wheel skids. This requires introduction of control engineering to upgrade control performance of the brake system on rolling stock. We are now studying a control method for mechanical brake that uses friction, a sort of non-linear element as the basis of brake force. One of our targets is to develop a brake control method that can control deceleration along with the decelerating pattern that optimizes riding comfort and prevents wheel skids. In this paper, a feedback control system of brake for decelerating pattern tracking is shown. At first, mathematical model of pneumatic cylinder and friction coefficient are made up with considering non-linear property, parameter changing and dead time. Next, Smith's method is intoroduced as compensation of dead time. Finally, control effects of this system are confirmed with numerical simulation and experimental results.
