Increased deceleration in high-speed and high-density train operation worsens riding comfort and frequently causes wheel skids. This requires introduction of the engineering to upgrade the control performance of the brake system on rolling stock. We are now studying a control method for the pneumatic brake that uses friction, a sort of nonlinear element, as the basis of brake force. One of our targets is to develop a brake control method that can control vehicle deceleration according to the decelerating pattern to optimize riding comfort and prevent wheel skids. We are designing a deceleration feedback control system as a tracking control method. This paper introduces simulation and experimental results of this control system.
