摘　　要：开关磁阻电机(switched reluctance motor,SRM)引入位置传感器使电机的结构变得复杂,同时降低了可靠性。为此,提出了一种基于电感空间矢量的新型无位置控制策略,将三相电感近似等效成正弦波,电机转子位置的估计则通过电感空间矢量的位置角得到。最后以TMS320F2812 DSP为控制核心对12/8极的开关磁阻电机进行了实验验证,其结果表明该方案可在整个速度范围内实现良好的无位置控制。The position sensor of SRM made its structure more complicate, at the same time reduced its reliability. Therefore, a new position sensorless control method of 3-phase SRM based on the inductance space vector was described. In this method, assuming the phase inductance waveform to be sine wave, the rotor position is obtained by computing the angle of the space vector of inductance. Finally, an experiment of three phase 12/8 SRM was designed based on TMS320F2812 DSP. The results of simulation show that the speed of SRM can be adjusted in full speed scope with the new method.
