| 摘 要： | 传统的简化磁链法需要以单相轮流导通和电流斩波控制为前提条件,其中单相轮流导通即在换相角处关断当前相的同时开通下一相的条件使系统的开通和关断角之间存在耦合,不利于在进行无位置传感器速度控制同时实现效率优化或转矩脉动最小化等要求。为此,本文提出了能够任意给定开通角且其与关断角无关的改进型简化磁链法,并以此搭建了开关磁阻电机(SRM)无位置传感器速度控制系统。所提方法仅需控制系统采取关断角固定和电流斩波控制方式,根据所提的改进型简化磁链法,能够确定关断角位置,并可估算出转速和任意时刻转子位置。最后,所提方法和利用该方法搭建的SRM无位置传感器速度控制系统,通过DSP驱动实验,证明了其有效性。

| Abstract: | In this paper,one sensorless speed control system of switched reluctance motor(SRM) based on the improved simplified flux method is investigated.The conventional simplified flux based sensorless method is valid with the condition of single phase alternate conducting and current chopping control.As a result,there is coupling between the turn-off period of off-going phase and turn-on period of in-coming phase.This coupling is not good for realizing optimal efficiency or minimize torque ripple in sensorless op... |
