摘要
开关磁阻电机(SRM)的位置传感器增加了电机结构的复杂性,且由于传感器分辨率的限制,导致系统高速运行性能下降。现有的检测方案大部分依赖于开关磁阻电机模型,起动和低速难以解决磁链积分误差问题。采用了一种新型的激励脉冲法控制方案,提出并分析了无位置传感器SRM控制策略,并在三相12/8极15 kW开关磁阻电机上进行实验验证。实验结果表明,该方案无需任何电机模型和参数,实现了开关磁阻电机的无位置传感器控制,具有良好的静动态性能。
The position sensor of switched reluctance motor （SRM） made its structure more complicate. Further more it may lead bad high-speed performance because of the low distinguishing of position sensor. Most available methods need the SRM model, and have flux linkage integral error in low speed, including zero speed. The paper adopted a novel method based on voltage pulse, position sensorless control strategy was proposed and analyzed, and finally, three-phase 12/8 pole SRM experiment was taken. Experiment result indicates that the operation of SRM without position sensor performs well in static and dynamic with the proposed method.
