    摘要: A method for Field Oriented Control (FOC) of a Permanent Magnet Synchronous Motor (PMSM) with a constant Power Factor Control (PFC) Loop includes measuring a rotor position of the PMSM. A plurality of stator voltages of the PMSM is controlled with a required direct (d)-axis current, a required quadrature (q)-axis current, the rotor position and a plurality of measured stator currents of the PMSM in a three-phase stationary reference frame. The required d-axis current is determined with a required power factor, the plurality of measured stator currents transformed into two-phase stationary reference frame, the measured stator currents transformed into a rotational reference frame, and each of a required α-axis voltage and a required β-axis voltage transformed into the two-phase stationary reference frame, wherein a power factor of the PMSM is controlled to be equal to the required power factor.
