System and method for wheel-slip prevention in railway vehicles with pneumatic brakes

A control system for wheel-slip prevention in a railway vehicle with a pneumatic brake, comprising:

• an input interface configured to accept a deceleration reference for controlling the pneumatic brake;
• a memory configured to store a reference governor providing executable instructions for modifying the deceleration reference upon 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;
• 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, wherein the memory is further configured to store an invariant set of combination of the deceleration reference and values of the state variables of the pneumatic brake, and wherein the reference governor predicts future violation of the wheel-slip constraint when current values of the state variables of the pneumatic brake and the deceleration reference are outside of the invariant set;
• and
• an output interface configured to output the sequence of control commands to control the pneumatic brake.
