An Improved Re-adhesion Control Method for High-speed Railways 2001-01-3255

Induction motor drive with pulse-width modulated (PWM) inverter control has been developed for the Korean High-Speed Railway. This paper describes a re-adhesion control system to improve tractive efficiency and to reduce wheel abrasion. The adhesion characteristics of the high-speed train are analyzed to get maximum adhesion effort and the re-adhesion control system is designed as a subsystem of the induction motor control. In order to verify the performance of the proposed system, a downscaled re-adhesion control simulator is set up and running tests are executed.
