基于虚拟降阶模型的LC滤波永磁同步电机驱动反电动势估计与无速度传感器控制

The installment of the $LC$ filter at the inverter output side reshapes the sinusoidal input voltage for the motor terminal, thus, extending a longer motor lifetime. Despite this, achieving speed sensorless control remains essential for enhanced reliability and saved costs. Currently, there is limited research on the development of a speed sensorless control tailored to high-order drive scenarios ...
