Research of PMSM Rotor Absolute Position Detection System Based on AU6802N1

Abstract:

Permanent magnet synchronous motor (PMSM) has the advantages such as high power density, simple structure and easy to maintain in the field of hybrid vehicle drive, and has been widely used in many areas. PMSM control methods include Space Vector Pulse Width Modulation (SVPWM), Direct Torque Control (DTC) and Maximum Torque per Current (MTPA) and so on. In these control methods, speed and accuracy of PMSM rotor absolute position detection is the key of its perfect control. The rotor absolute position information is more accurate, the amplitude of its torque ripple will be lower, which means better performance of PMSM control. In this paper, a PMSM rotor absolute position detection system based on AU6802N1 has been designed and produced, and laid a solid foundation for its calibration and improvement.
