[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.
