Full-Speed Range Encoderless Control for Salient-Pole PMSM with a Novel Full-Order SMO

Full-Speed Range Encoderless Control for Salient-Pole PMSM with a Novel Full-Order SMO

For salient-pole permanent magnet synchronous motor (PMSM), the amplitude of extended back electromotive force (EEMF) is determined by rotor speed, stator current and its derivative value. Theoretically, even at extremely low speed, the back EEMF can be detected if the current in q-axis is changing....
