一种新型的开关磁阻电机无位置控制策略研究

The Study of A New Control Strategy about Switched Reluctance Motor Without Position Sensor

研究了一种无位置传感器的系统运行控制策略,探讨了无位置控制的原理,并以DSP(digital signal processor)为核心,以三相(12/8)开关磁阻电机为执行对象,设计了系统的硬件和软件。通过样机试验,结果表明运用该控制策略的开关磁阻电机系统能够较快地预测转子位置,并且在中低速范围内位置检测准确,系统运行稳定。

Studies a control strategy of SRD without position sensor and discusses its principle. With DSP as the core and three phases 12/8 SRM as the implementing object, designs software and hardware of SRD without position sensor. After the examination on the sample SRD without sensor, the results show that the sample SRD can fastly and correctly compute the rotor pisiton, especially when the motor runs at mid-speed and low-speed.
