Abstract :
According to the requirement of urban rail vehicles, the rare earth permanent magnet brushless DC traction control system in city rail is designed based on TMS320F2812. The hardware block diagram and design methods are presented. The position feedback signal is adopted as motor commutation foundation. The PID control strategy of closed-loop electric current is used in the system. This system has some characteristic as follows: simple structure, high accurate controlling, Strong real time, etc. It is showed by the prototype testing that the system is reliability and reasonable.
