摘要

研究并成功实现了一种基于监测开关磁阻电机相电流上升时间的闭环控制技术。在这种技术中，增量相位电感在SR电机的变化是用来检测转子的位置。采用硬线数字电路实现了基于电流波形的转子位置检测控制电路。本文给出了将该方法应用于4 kW带IGBT驱动的四相SR电机的转矩-速度和系统效率特性。

Switched reluctance motor drive without direct rotor position sensing

A closed loop control technique based on monitoring phase current risetime for switched reluctance (SR) motors without direct rotor-position sensors has been studied and implemented successfully. In this technique the variation in incremental phase inductance in a SR motor is used to detect rotor position. A control circuit for current-waveform-based rotor position detection has been implemented using hard-wire digital circuits. Torque-speed and system-efficiency characteristics resulting from the application of the method to a 4 kW, four-phase SR motor with an IGBT drive are presented.<>
