摘要
分析了开关磁阻电机的突出优点是结构简单，控制灵活，而机械式位置传感器的存在使这一优点变得逊色；给出了取消位置传感器的开关磁阻电机位置闭环控制方案，该方案以８７５１单片机为核心，利用检测定子相电感变化确定转子位置，降低了成本，提高了控制可靠性。
A prominent advantange of the switched reluctance motor is flexible control with simple construction.However,the mechanical rotor position sensor has been a major complaint in variable inverter drives as it is expensive,fragile,and can prevent use in hostile environments.A sensorless closed-loop speed control for the switched reluctance motor is presented.Single-chip microcontroller(8751),as the core of this scheme,defines the rotor position by means of measuring stator phase inductance,hence the production costs are reduced and the reliability of control is improved.
