摘　　要：在两相混合式步进电机调速系统中,为提高调速系统的快速响应时间和稳定性,在双闭环的矢量控制策略中,速度环采用超螺旋滑模与自抗扰控制结合(STSM-ADRC)控制策略。对线性自抗扰控制器中的状态误差反馈控制器和跟踪微分控制器进行超螺旋滑模算法优化,并采用李雅普诺夫函数进行稳定性证明。仿真结果显示:电机运行转速可以达到毫秒响应时间且无超调,有效提高了步进电机调速系统的快速性和鲁棒性。In the two-phase hybrid stepper motor speed control system,in order to improve the fast response time and stability of the speed control system,the combination of super-twisting sliding mode and active disturbance rejection control(STSM-ADRC)control strategy was used in the velocity loop in the vector control strategy of double closed loop.Optimisation of super-twisting sliding mode algorithm for state error feedback control and tracking differentiator control in linear active disturbance rejection control,and the stability was proved by using the Lyapunov function.The simulation results show that the motor running speed can reach millisecond response time without overshooting,which effectively improves the rapidity and robustness of the stepper motor speed control system.
