摘要

基于扩展卡尔曼滤波(EKF)技术的无传感器驱动得到了深入的研究和发展。公认的一个主要弱点是它们的参数敏感性。研究了递归参数辨识(RPI)方法在永磁同步电机电气参数在线估计中的应用。良好近似值的可用性增加了EKF的鲁棒性，从而导致驱动器的优越性能。

On-line parameter commissioning in sensorless PMSM drives

Sensorless drives based on extended Kalman filter (EKF) techniques are deeply studied and developed. It is acknowledged that one major weak point is their parameter sensitivity. This paper investigates the application of a recursive parameter identification (RPI) method to the online estimate of the electrical parameters of permanent magnet synchronous motors (PMSM). The availability of well-approximated values increases the robustness of the EKF, and leads thus to superior performances of the drive.
