Research on SelfCalibration Algorithm of HallEffect Sensor forPermanent Magnet Synchronous Motor

In order to improve the efficiency of permanent magnet synchronous motor (PMSM) with halleffect sensor, it was necessary to solve the difficulty of halleffect sensor calibration. Two selfcalibration algorithms were proposed. In order to verify the accuracy of the two selfcalibration algorithms, simulation and algorithmic programming verification of the proposed algorithm were presented. After calibrated by algorithms, the rotor position of the halleffect sensor was compared with that measured by the resolver. The results showed that the selfcalibration algorithms of halleffect sensor could improve the calibration efficiency and improve the accuracy of the rotor position, and provide the guarantee for accurate and efficient control of the PMSM.
