摘    要:对近年提出的多种估算永磁同步电动机转子位置、速度的方法进行了综述,比较了各种方法的优缺点;并对中高速适用的扩展卡尔曼滤波(EKF)进行了实验研究:零速及低速时,现有的永磁同步电动机无传感器技术多是指无位置传感器,少数几种无速度估计算法都有很大的局限性.本文针对这一现状,选取基于高频信号注入+磁链观测的永磁同步电动机全速范围无传感器控制方法进行了仿真验证;最后指出复合控制方法是实现全速范围无传感器控制技术的发展趋势.

关 键 词:永磁同步电动机  无传感器  信号注入  复合磁链模型  观测器  卡尔曼滤波

Abstract:Various methods of estimating the rotor position and speed for permanent magnet synchronous motor(PMSM) drive are reviewed in this paper,and both the advantages and disadvantages are also compared respectively.Next,extend Kalman filter,adequate for middle and high speed,is verified.Most of the sensorless schemes are position self-sensing at zero and low speed,with few speed sensorless schemes adequate for low speed having significant limitations.A novel sensorless scheme application in whole speed based on ...
Keywords:Permanent magnet synchronous motor(PMSM)  sensorless  signal injection  combined flux linkage model  observer  Kalman filter
