Abstract
This paper presents an improved rotor position estimation method for surface permanent magnet synchronous motor (SPMSM) using a low-resolution Hall-Effect sensor. Firstly, an observation function is proposed to detect the speed variation, and a novel correction method based on optimization process is proposed to identify and correct the deviation angle caused by sensor misalignment. Then, an improved position observer is introduced using a gain-scheduling controller to achieve better performance in both steady state and transient state. The proposed method enhances the anti-perturbation and start-up capability for SPMSM and compensate the misalignment effect of Hall-Effect sensors. Experimental results are demonstrated to verify the effectiveness of the proposed method.
