Velocity Servo Design of Auto-disturbance-rejection Controller for Permanent-magnet Synchronous Motor Servo System Based on Feedforward Compensation Controller Including Sliding Mode

摘要

To solve the horizontal speed of shear blade demanded strictly maintain synchronous speed with plank in shear zone, a feedforward compensation controller including sliding mode controller is proposed as the velocity controller to improve the system performance, which has the merit of the small chattering and good robustness. The simulation shows that this method improve dynamics and robustness of system effectively despite of load abrupt change and system parameter change.
