为提升永磁同步电机调速系统中的动态响应性能和抗扰性能，提出了一种改进型超螺旋滑模线性自抗扰控制（STSM-LADRC）策略。该策略利用滑模变结构原理对LADRC中的线性扩张状态观测器（LESO）和线性状态误差反馈（LSEF）控制律进行优化。首先，设计了STSM-LESO，采用STSM控制算法对LADRC中的LESO进行改进，以提高观测器观测性能从而增强控制器的抗干扰能力；其次，利用STSM控制算法代替原有的LSEF控制律，提高控制器的动态响应性能，同时使用tanh函数替换超螺旋滑模算法中的sign函数进一步削弱滑模固有抖振，提高系统的稳定性；然后，使用李雅普诺夫理论对所提控制策略进行稳定性分析；最后，基于Matlab/Simulink仿真平台进行验证。仿真结果表明，与传统的LADRC和其他控制器相比，所提控制策略具备更好的动态响应性能和抗扰性能。

To improve the dynamic response and disturbance rejection property of the permanent magnet synchronous motor (PMSM) speed regulation system, an improved super-twisting sliding mode linear active disturbance rejection control (STSM-LADRC) strategy was proposed. This strategy optimized the linear extended state observer (LESO) and linear state error feedback (LSEF) control law in LADRC using the sliding mode variable structure principle. First, the STSM-LESO was designed, where the STSM control algorithm improves the LESO in LADRC, enhancing the observing property and thus the controller's disturbance rejection property. Second, the STSM control algorithm replaced the original LSEF control law, improving the controller's dynamic response property. The hyperbolic tangent function was used instead of the sign function in the STSM algorithm to further reduce inherent sliding mode chattering and enhance system stability. The proposed control strategy was then analyzed for stability using Lyapunov theory. Finally, s
