ABSTRACT
Adhesion plays a significant role in railway traction and loss of adhesion results in an undesirable phenomenon known as wheel slip in an accelerating locomotive. The states of art, conventional wheel slip control method use slip velocity as control variable to bring output motor torque reduction to arrest wheel slip. Absence of accurate and precise train velocity measurements affects the real time performance of conventional control as it suffers from some of the major setbacks which are categorised as False Negative and False Positive wheel slip occurrences in the confusion matrix for wheel slip controller. This study discusses wheel slip control method utilising adhesion value existing between rail and wheel to arrest wheel slip with substantial reduction in occurrence of False positive and False Negative wheel slip cases.
