摘要

本文研究了转子参照系下基于反电动势估计方法的内嵌式永磁同步电动机(IPMSM)无速度和位置传感器控制的暂态性能。利用IPMSM的数学模型分析了估计的反电动势、位置和速度分量的基本特性。所分析的无传感器控制具有反电动势估计器、转子位置估计器(如锁相环(PLL)型估计器)和扰动观测器。为了提高暂态稳定性，介绍了无传感器控制算法和采用电流反馈控制的角度补偿方法等主要因素的选择方法。仿真和实验结果验证了该策略在瞬态下的动态性能。

The study on transient performance improvement of position sensorless control algorithm for IPMSM

This paper presents a study of the transient performance of the speed and position sensorless control of an interior permanent magnet synchronous motor (IPMSM) based on back-electromotive force (back-EMF) estimation method in the rotor reference frame. The fundamental characteristics of the estimated back-EMF, position and speed components using mathematical models of the IPMSM are analyzed. The analyzed sensorless control has back-EMF estimator, rotor position estimator such as a phase-lock-loop (PLL) type estimator, and disturbance observer. To improve the transient stability, the selection methods of major factors such as for sensorless control algorithm and the angle compensation method using a current feedback control are introduced. The dynamic performance of the proposed strategy in transient state is verified through simulation and experimental results.
