초록

In this paper an improved re-adhesion control scheme is proposed for IC4M(1-Controller 4-Motors) traction system. It is well known that the coefficient of adhesion between wheel and rail has a maximum value at a certain slip velocity. In the proposed scheme, maximum adhesive force is estimated by an observer and the driving torque of motor is controlled to set maximum adhesive force. The simulation results are presented.
