This paper presents a novel re-adhesion control method suitable for a single-inverter multiple-induction-motors drive system for the train traction, which can suppress the slip-slide phenomenon by adjusting the torque command for the motors according to the estimated adhesive forces between wheels and rails. Performance of the proposed control method applied for the Shinkansen traction system is predicted by digital simulations. Experimental results with a miniature experimental equipment, which can simulate the real rolling stock traction system, prove its effectiveness for the Shinkansen traction system.
