چکیده
This paper proposes a novel extended electromotive force (EEMF) observer of dual three-phase permanent magnet synchronous motor (DTP-PMSM) operable to the position sensorless overmodulation drive. The drive occurs in current harmonics, and estimated EEMF also contains harmonic components, leading ripple error position. Based on vector space decomposition (VSD) utilized DTP-PMSM control, proposed method can decrease harmonics components EEMF, it improve estimation. effectiveness improvement estimation were experimentally verified.

This paper proposes an improved sensorless control to estimate the rotor position of an interior permanent magnet synchronous motor. A phase-locked loop (PLL) is used to obtain the phase angle of the grid. The rotor position can be estimated using a PLL based on extended electromotive force (EEMF) because the EEMF contains information about the rotor position. The proposed method can reduce the...
