Abstract
A control system for wheel-slip prevention in a railway vehicle with a pneumatic brake is provided. The control system comprises an input interface configured to accept a deceleration reference for controlling the pneumatic brake, and a memory configured to store a reference governor providing executable instructions for modifying the deceleration reference upon its violation of a wheel-slip constraint, and configured to store a controller providing executable instructions for mapping the modified deceleration reference to a sequence of control commands for controlling pressure applied by the pneumatic brake. The control system further comprises a processor configured to execute the reference governor to modify the deceleration reference and configured to execute the controller to map the modified deceleration reference to the sequence of control commands. Further, an output interface of the control system is configured to output the sequence of control commands to control the pneumatic brake.
