基于正交电压模型观测器的感应电机无速度传感器驱动宽速域稳定性提升

The stability in both low-speed range and high-speed range are one of the major challenges of sensorless induction motor drives. This article proposes the wide-speed range stability solution from the perspective of the orthogonality voltage-model (VM). First, the mathematical expression of VM is reconstructed by considering the orthogonality of rotor flux, and an extended state observer is establi...
