一种基于自适应直接磁链幅值估计的改进闭环电压模型观测器在感应电机无传感器预测直接电压控制中的应用

Voltage model observer is a simple and economical technique for flux estimation in induction motor sensorless drives. However, it shows poor performance in low-speed regions. Therefore, in most cases, the use of this observer is limited. On the other hand, using a simple but accurate estimator is important when the control method is sophisticated and requires heavy computation. This issue will be ...
