【摘要】：针对内嵌式永磁同步电机无速度传感器控制下的重载起动问题,提出了基于相位滞后补偿的高频旋转电压信号注入法,设计了精确观测模型,并对数字滤波器产生的相位滞后进行了准确补偿。该方法将永磁同步电机的无速度传感器控制的应用范围扩展到了零速和低速范围。仿真结果表明,提出的新观测器可以准确观测转子位置,起动瞬间就可以获得大的电磁转矩,实现了永磁同步电机无传感器控制下的重载起动。
[Abstract]:Aiming at the heavy load starting problem of embedded permanent magnet synchronous motor (PMSM) without speed sensor control, a high frequency rotation voltage signal injection method based on phase lag compensation is proposed, and an accurate observation model is designed. The phase lag generated by digital filter is compensated accurately. This method extends the speed sensorless control of PMSM to zero speed and low speed range. The simulation results show that the proposed new observer can accurately observe the rotor position and obtain a large electromagnetic torque at the moment of starting, and realize the heavy-load starting of the permanent magnet synchronous motor under sensorless control.
