无速度传感器的动车组牵引电机控制算法

摘要

针对目前动车组牵引电机的控制算法中速度信号的获取方法在工艺安装、电磁兼容以及可靠性等方面存在难度的问题,提出了一种基于无速度传感器的动车组牵引电机控制算法,摆脱了原有控制算法中对速度信号的依赖,即通过建立转子磁链观测模型和转速估计数学模型,对动车组的牵引电机进行矢量控制,仿真结果表明,该算法能得到良好的控制效果.%A method based on non-speed-sensor is presented in view of the cu EMU traction motor control algorithm of speed signal acquisition in the process of installation, electromagnetic compatibility and reliability. Through the establishment of rotor flux model and the mathematical model of rotor, EMU traction motor vector control is used, and simulation results show that this algorithm can obtain good control effect.
