Extensive research has shown that the control technique of permanent magnet synchronous motors (PMSMs) is relatively mature using high precision position sensors with the penalty of high hardware cost. On the other hand, the sensorless control has demonstrated many advantages, but its application with heavy loading is limited. In this paper, a rotor position correction method using low-resolution Hall-effect sensors is proposed, which shows the advantage of low cost and high estimation precision. The exact discrete-time voltage equation model is utilized to obtain accurate speed information, and a speed estimation observer with average speed calculated using Hall signal is adopted to make rotor position converge to exact location. Simulation verifies the effectiveness of the method including the steady and dynamic performance.
