Vector Control of Stepper Motor Based on Super-twisting Sliding Mode Active Disturbance Rejection
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 dis-turbance 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.
