为了提高表贴式永磁同步电机（SPMSM）无传感器控制系统的精度和稳定性，针对传统PI控制存在鲁棒性不足的问题，提出了一种采用带有线性校正项的快速超螺旋滑模模型参考自适应系统观测器（FSTA-SM-MRASO）。所提观测器将快速超螺旋算法（FSTA）与模型参考自适应系统（MRAS）观测器相结合，构建了基于FSTA-SM-MRASO的SPMSM无传感器矢量控制系统。通过MATLAB/Simulink平台进行仿真，验证了所提策略的有效性。

In order to improve the accuracy and stability of sensorless control system of surface-mounted permanent magnet synchronous motor (SPMSM), a fast super twisting sliding mode model reference adaptive system observer (FSTA-SM-MRASO) with linear correction is proposed to solve the problem of insufficient robustness of traditional PI control. The proposed observer combines the fast super twisting algorithm (FSTA) with the model reference adaptive system (MRAS) observer to construct the sensorless vector control system of SPMSM based on FSTA-SM-MRASO. The effectiveness of the proposed strategy is verified by simulation on the MATLAB/Simulink platform.
