Abstract

This paper presents a comparison about phase estimation between Hall sensors and sliding mode observer (SMO). The phase estimation result corresponds to the control effect of Permanent-magnet Synchronous Motor (PMSM). Low-resolution Hall-effect sensor is widely used in PMSM because of its good comprehensive performance. Sliding mode observer is a frequently-used algorithm of PMSM sensorless control. The rotor phase estimated by Hall sensors has a good steady-state performance but some ripple or chattering components occur when the rotor is accelerating, decelerating or fluctuating. As a contrast, the phase estimated by SMO has an attractive robustness to speed fluctuation as well as parameter variations but the estimation result has some vibrations under steady condition which is caused by the SMO algorithm itself. This paper contrasts the SMO with Hall sensors in view of control effects both under starting state, steady state and speed fluctuation state. The comparison is illustrated by the phase estimation results and the phase currents response. All the work is realized by Matlab/Simulink and the simulation results show the relative merits of SMO and Hall sensors.
