摘要

在介绍异步电机速度辨识原理的基础上，分析了辨识算法的稳定性、模型电压误差和模型定子电阻值偏差，以及在极低速工况下对速度辨识在地铁牵引应用中的影响；采用定子电阻在线修正和基于逆变器模型的电压误差在线补偿，减小了转速辨识误差，提高了极低速工况下的转速辨识精度，仿真和试验验证了方案能满足地铁车辆运行需求。

Abstract

Based on the principle of induction motor speed estimation, the stability of the estimation algorithm was analyzed, as well as the influence of voltage error and stator resistance error in motor model on speed estimation at very low speed condition in subway traction applications. Stator resistance online correction and voltage error online compensation based on inverter model was used for reducing the speed estimation error and improving the speed estimation accuracy at very low speed condition. Simulation and experiment verified the proposal to meet the requirement of metro vehicle running.
