摘　　要：分析了高速列车牵引传动系统因轮径差异和牵引电机参数偏差而出现的负荷分配不平衡现象,提出了一种基于加权法的线性拟合控制策略,与传统的主从控制策略相比,该策略能够均衡牵引电机的出力。基于Matlab/Simulink建立的CRH2型高速列车牵引传动系统仿真模型进行了仿真,验证了理论分析的正确性。分析结果将为牵引电机选型匹配提供依据。The load unbalanced distribution status of traction motors in high-speed train was analyzed due to the wheel diameter deviation and motor parameter deviation. To this problem, a control strategy based on weighted linear regression was proposed. Compared to the traditional master-slave control strategy, it can yield better performance to balance the traction motorsr output. By established simulation model of CRH2 trac- tion driver system based on Matlab/Simulink, the simulation results were obtained and validate the theoretical analysis. The research provides good recommendations about how to select matched traction motors.
