基于离散速度自适应全阶观测器的弱磁区感应电机无速度传感器控制

This paper presents a novel field-weakening strategy combined with a modified discrete speed-adaptive full-order observer to improve the performance of speed-sensorless induction machine drives in the field-weakening region. The robust field-weakening controller regulates the field current and the clamp of torque current according to the machine operating mode. Compared with the conventional inver...
