This paper presents an improved rotor positionestimation method for surface permanent magnet synchronousmotor (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 processis proposed to identify and correct the deviation angle causedby sensor misalignment. Then, an improved position observer isintroduced using a gain-scheduling controller to achieve betterperformance in both steady state and transient state. Theproposed method enhances the anti-perturbation and start-upcapability for SPMSM and compensate the misalignment effectof Hall-Effect sensors. Experimental results are demonstrated toverify the effectiveness of the proposed method.
