摘要/Abstract

摘要： 针对采用线性霍尔元件检测直线电机动子的磁场进而通过磁场信息来解算电机位置的方法，通过介绍双霍尔传感器位置检测的原理，分析由安装误差造成解算位置偏差的机理。提出采用三轴霍尔传感器代替线性霍尔传感器的方法，实现霍尔线性影响因素的误差补偿。为了降低非线性干扰造成的位置解算误差，提出了模糊-神经建模方法来实现传感器的离线标定，最后通过仿真和实验证明了所提传感器误差补偿方法的有效性。

Abstract: There was a way to detect the positions of linear motors by detecting the magnetic field informations of linear motor movers. The principle of double Hall sensor position detection was introduced, and the cause of the installation errors was analyzed herein. In order to achieve the Hall sensor position detection error compensation, a method of using a 3D Hall sensor was proposed instead of a linear Hall sensor. In order to reduce external interferences, a fuzzy-neural off-line modeling method was proposed. Finally, the correctness of the compensation method was verified through the simulations and experiments.

Key words: permanent magnet synchronous linear motor(PMSLM), 3D Hall sensor, position sensor, fuzzy contro
