Voltage-current dual-model fusion-based sensorless control of PMSM using effective flux linkage
Abstract
Abstract To address DC offset and poor low-speed accuracy of traditional flux observers in PMSM sensorless control, this paper proposes a voltage-current dual-model fusion-based effective flux observer. It integrates the voltage model’s simplicity and the current model’s excellent low-speed performance, adopts a PI regulator to process inter-model errors and output compensation signals for flux correction, and introduces effective flux to simplify rotor position extraction. Simulation results verify the strategy’s superiority in position/speed identification accuracy and dynamic performance.
