摘　　要：电动汽车的驱动电机在与制动系统协调控制的情况下,其动态转矩响应能快速准确地进行防抱死制动,但车辆的传动性能会影响电机的控制性能。考虑传动对纯电动汽车动态制动过程的影响,提出一种新型的永磁同步电动机(Permanent Magnet Synchronous Motor,PMSM)矢量控制方法。建立电动汽车的动力学模型,分析传动弹性和间隙非线性对电机制动力矩的影响。以防抱死制动的车轮滑移比为基础,提出基于间隙滑移补偿和弹性双闭环PID(Proportional Integral-Derivative)补偿的电机转矩控制换模方法。实验结果表明,永磁同步电动机开关控制能够有效补偿变速器,通过快速准确的电机转矩调节,显著提高电动汽车防抱死制动的舒适性、稳定性和可操作性。When the driving motor of electric vehicle is controlled in coordination with the braking system,its dynamic torque response can carry out anti-lock braking quickly and accurately,but the transmission performance of the vehicle will affect the control performance of the motor.Considering the influence of transmission on the dynamic braking process of pure electric vehicle,a new vector control method of permanent magnet synchronous motor(PMSM)is proposed.The dynamic model of electric vehicle was established.The influence of transmission elasticity and clearance nonlinearity on motor braking torque was analyzed.Based on the wheel slip ratio of anti lock brake,a method of motor torque control mode change based on gap slip compensation and elastic double closed-loop PID compensation was proposed.The experimental results show that the PMSM switch control can effectively compensate the transmission,and improve the comfort,stability and operability of the anti-lock braking of the electric vehicle by fast and accurate motor torque regulation.
