摘　　要：同步磁阻电机是一种结构简单耐用、造价较低的特殊同步电机,近年来逐渐受到关注。将旋转高频电压注入法无位置传感器控制技术应用于同步磁阻电机,研究无带通滤波器同步磁阻电机位置辨识策略,以简化控制算法,降低位置辨识误差,减轻处理器的运算压力。同时在实验中,分奇偶周期分别注入基波电压和高频电压,以充分利用实验电源容量。在Matlab/Simulink环境下搭建仿真模型,同时搭建1.2 kW样机的硬件测试平台,仿真和实验结果都验证了简化的无位置传感器矢量控制算法的有效性和准确性。Synchronous reluctance motor is a special synchronous motor with simple,durable structure and low cost,which has attracted more and more attention in recent years.The sensorless control technology of rotating high-frequency voltage injection method was applied to synchronous reluctance motor,and the position identification strategy of synchronous reluctance motor without band-pass filter was studied to simplify the control algorithm,reduce the position identification error and the operation pressure of processor.In the experiment,fundamental voltage and high-frequency voltage are injected separately in odd and even cycles to fully utilize the experimental power supply capacity,and in the experiment,fundamental voltage and high-frequency voltage were injected separately in odd and even cycles to fully utilize the experimental power supply capacity.The simulation model was built on Matlab/Simulink environment.Besides,the hardware test platform of 1.2kW prototype was built.The simulation and experimental results both verify the effectiveness and accuracy of the simplified sensorless vector control algorithm.
