摘　　要：为提升电机车停车的稳定性和精准性,实现精准制动,采用了基于模糊PID的电流环、转矩环的双闭环矢量控制永磁同步电机。在不同初始停车速度下,10次停车距离误差最大为-0.16 m;在不同停车距离下,11次停车距离误差最大为-0.19 m;在不同坡度下,7次停车距离误差最大为0.21 m。上述误差均小于±0.3 m,说明该停车控制方法能够有效实现电机车的精准停车。In order to improve the stability and accuracy of electric locomotive parking,accurate braking is realized,a double closed-loop vector control permanent magnet synchronous motor based on fuzzy PID current loop and torque loop is adopted.At different initial stopping speeds,the maximum error of 10 stopping distances is-0.16 m.At different parking distances,the maximum error of 11 parking distances is-0.19 m.At different gradients,the maximum error of 7 stopping distances is 0.21 m.The above errors are all less than ±0.3 m,indicating that this stopping control method can effectively realize accurate stopping of electric locomotives.
