摘要

提出了一种基于定子相电压三次谐波分量确定气隙磁通螺旋位置的同步磁阻电机直接磁场定向控制器。该控制利用了机器在饱和状态下运行时在气隙磁通中产生的以同步频率旋转的空间饱和谐波分量。当机器连接时，三相电压的总和产生由三次谐波分量主导的信号。利用这个信号，实现了一个完全无传感器的驱动，可以成功地从零速度同步启动磁阻电动机。大量的实验结果显示了不同估计方案的效果，并给出了从谐波电压信号中检测磁链位置的实际问题。

Position sensorless synchronous reluctance motor drive using the stator phase voltage third harmonic

A direct field orientation controller for synchronous reluctance motors based on determination of the spiral position of the air gap flux from the third harmonic component of the stator phase voltages is presented. The control utilizes the spatial saturation harmonic components rotating at synchronous frequency that are generated in the air gap flux when the machine operates in a saturated condition. When the machine is wye connected, the sum of three-phase voltages results in a signal dominated by the third harmonic component. Using this signal, a completely sensorless drive is implemented which can successfully synchronously start the reluctance motor from zero speed. Extensive experimental results showing the effect of different estimation schemes and practical problems of detecting the flux position from the harmonic voltage signal are presented.<>
