ABSTRACT:
A locomotive traction controller system using fuzzy logic to maximize the coefficient of friction between locomotive drive wheels and the rail on which the wheels ride. The locomotive traction system includes a fuzzy logic slip controller that provides a generator reference signal to a generator controller that controls the field current of the generator of the locomotive. The fuzzy logic slip controller regulates to a predetermined wheel slip regardless of the rail condition. A fuzzy logic slip reference estimator applies a wheel slip reference signal to the fuzzy slip controller depending on the rail condition in order to adjust the generator reference signal and thus modify the wheel slip to maximize the coefficient of friction.
