Abstract: In order to improve performance of battery electric locomotive in coal mine, reduce energy consumption and improve work efficiency, a kind of control system of mine-used switched reluctance electric locomotive based on ARM was designed. The system uses control mode combing angular position control and chopped voltage control, adopts control strategy of torque distribution function, and achieves control of the battery motor vehicle combined with speed and current dual closed-loop system. The experimental results show that the system has small torque ripple, high efficiency, strong robustness and good performance of speed adjustment.
