摘　　要：有效地控制横向磁场直线开关磁阻电机(TFLSRM)的牵引力和法向力,使两者的脉动均减小,是实现半磁悬浮式城轨交通车辆TFLSRM牵引系统必须要解决的难点。文章基于开关磁阻电机(SRM)的直接转矩控制(DTC)理论,提出了同时控制TFLSRM牵引力和法向力的方法。仿真结果表明,该控制方法合理、有效。To realize the transverse flux linear switched reluctance motor （TFLSRM） based traction system for half-maglev urban rail transit vehicle, that the traction force and normal force are controlled simultaneously to minimize their ripple is one of key problems to be resolved. Based on the analysis of SRM direct torque control, a method is proposed to simultaneously control traction and normal force of TFLSRM. Simulation results show the control method is reasonable and effective.
