摘要
文章主要研究了如何利用DSP芯片实现无刷直流电动机无位置传感器调速系统 ,引入一种基于电动机三相绕组端电压变化规律的电机电流换相理论 ,使直流无刷电动机无位置传感器控制策略由传统的反电势过零点法进入一个新阶段 。
This paper is mainly about how to use DSP to realize the sensorless BLDCM speed-adjustment system.A new current commutation theory based on analyzing the three-phase voltages is introduced. Compared with the traditional back-EMF method, it greatly improves the control system performance and brings about a new prospect for BLDCM.
