基于广义比例积分观测器和卡尔曼滤波的永磁同步电机无传感器控制方案

Since conventional linear extended state observer (LESO) can only cope with the zero-order disturbance, the sensorless control scheme based on LESO lacks the ability to accurately estimate the back electromotive force (BEMF), and the estimation accuracy of rotor position and speed is limited. In this article, a new composite sensorless control scheme for permanent magnet synchronous motor drive vi...
