基于频率自适应线性扩张状态观测器的双三相内置式永磁同步电机无传感器控制

The sensorless control of interior permanent magnet synchronous motor based on the conventional linear extended state observer (LESO) does not have sufficient capability to eliminate the steady-state position estimation error. To solve this issue, a frequency adaptive LESO (FA-LESO) is proposed to estimate the back electromotive force accurately. The gains of the proposed observer are designed acc...
