Research on sliding mode active disturbance rejection based on permanent magnet synchronous motor

Abstract The motor is more and more common in our daily life, because the permanent magnet synchronous motor has many advantages such as high efficiency, simple structure and reliability. For the motor speed response time is long, overshoot and load instability. The motor speed loop controller is designed by combining the mathematical model of a permanent magnet synchronous motor with sliding mode control theory and nonlinear active disturbance rejection control theory. By combining with ADRC, this method has the characteristics of small overshoot, small buffeting, very fast response and strong anti-load disturbance ability. The feasibility of the sliding mode active disturbance rejection control algorithm is verified by Matlab/Simulink simulation experiments.
