摘要

本文利用换向信号与反电动势的关系,提出了一种基于信号的三相无刷直流电机转速估计方法。这两种信号都可以从电机端子的每个相位直接测量。对两个信号之间的关系函数进行近似和滤波,求出相电压交叉点的轴,并利用人工智能求出各转速的函数系数和滤波器参数。

AI-based sensorless speed estimation of 3-phase BLDC motor
This paper describes a signal-based speed estimation of 3-Phase Brushless Direct Current (BLDC) motor using the relationship between commutation signal and Back Electromotive Force (Back-EMF). Both signals can directly be measured from each phase of motor's terminal. The relationship function between both signals is approximated and filtered to find Haft of phase voltage-Crossing Point and using Artificial Intelligence find coefficient of function and filter's parameters of each speed.
