摘要

本文研究了无传感器内嵌式永磁同步电机驱动的实验实现。该电机已专门设计，以获得一个宽的磁通减弱区域，以尽量减少驱动功率额定值，尽管在一个宽的速度范围。通过扩展卡尔曼滤波(EKF)得到转子的位置和角速度。该估计算法既不需要知道机械参数，也不需要知道转子的初始位置。在本文中，特别强调的是控制算法，这是复杂的电机各向异性，并已专门研究，以提高整体系统性能。

EKF-based sensorless IPM synchronous motor drive for flux-weakening applications

The paper deals with the experimental realisation of a sensorless interior permanent magnet (IPM) synchronous motor drive. The motor has been specifically designed to get a wide flux-weakening region, to minimise the drive power rating in spite of a wide speed range. Position and angular speed of the rotor are obtained through an extended Kalman filter (EKF). The estimation algorithm requires neither the knowledge of the mechanical parameters, nor the initial rotor position. In the paper, particular emphasis is placed on control algorithms, that are complicated by the motor anisotropy and that have been specifically studied to enhance the overall system performance.
