摘要
研制了基于3次谐波检测法[1]的无位置传感器无刷直流电动机微机控制系统,实现了开环控制、转速负反馈控制以及电压负反馈加电流正反馈控制三种调速控制方式,对三种调速方式及实验结果进行了分析和比较。
We design a microcomputer control system of positon-sensorless BLDCM by detecting the third harmonic signal of back-emf and realize three speed control modes, which are opening control, speed negative feedback control and voltage negative feedback coupled with current positive feedback control.Then three speed control modes and experiment results are analyzed and compared.
