Abstract: Aiming at the difficulties in parameter tuning of the traditional active disturbance rejection controller (ADRC) and the poor performance when the rotational speed varies in the permanent magnet synchronous motor (PMSM) position sensor-less control, the proposes a bandwidth-adaptive linear active disturbance rejection controller (BALADRC) . Additionally, to overcome the instability caused by the constant gain parameters of the traditional Super-Twisting sliding mode observer (STSMO) , a Fuzzy adaptive variable parameter Super-Twisting sliding mode observer (FSTSMO) was proposed. Fuzzy control was utilized to adaptively optimize the observer ' s parameters, enhancing system robustness and stability. By integrating the BALADRC and FSTSMO, an optimized sensorless vector control system for PMSM was constructed. Simulation results verify the feasibility and effectiveness of the proposed method under varying rotational speed conditions.
