基于自适应增益的全阶终端滑模观测器的城市轨道交通直线感应电机无速度传感器控制

Speed sensorless control is essential for linear induction machines (LIMs) in urban rail transit. However, it is difficult to obtain the accurate speed when the mutual inductance of LIM is changed nonlinearly due to the end effect, especially in high-speed flux-weakening region. To enhance the robustness of the sensorless control system against such parameter changes, an improved speed sensorless ...
