基于饱和嵌入式电感回归的内嵌式永磁同步电机无传感器全转矩启动

To enable full-torque sensorless startup for interior permanent magnet synchronous motors, this letter presents a paradigm shift from passive saturation compensation to active exploitation of saturation-induced inductance. By encoding magnetic saturation characteristics into pulsating-voltage models and using a nonlinear observer to estimate the inductance regression, the method achieves accurate ...
