基于滑模观测器的永磁同步电机无传感器控制方法综述

For permanent magnet synchronous machines (PMSMs), high-performance control strategies rely on sensors to obtain accurate information of rotor position and speed. However, mechanical sensors are expensive and susceptible to harsh environment. Therefore, various sensorless control strategies have been proposed and intensively investigated for decades. Among them, sliding mode observer (SMO) based s...
