摘要：
This article presents an improved rotor position estimation method for surface permanent magnet synchronous motor (SPMSM) using a low-resolution Hall-effect sensor. First, 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 antiperturbation and startup capability for SPMSM and compensate the misalignment effect of Hall-effect sensors. Experimental results are demonstrated to verify the effectiveness of the proposed method.
