Sensorless Rotor Position Determination of PSMS Focusing on HF Signal Injection Method

Abstract

The paper deal with HF injection method for rotor position determination of sensorless permanent magnet sychronoous motor (PMSM) drive. Special attention is paid to generation - and injection of HF signal as well as to filtering of positive component of current HF vector. The results of simulation experiments verify suitably of used method for whole intended range of motor angular speed.
