Control and Simulation of the Velocity Servo System for Brushless DC Motor based on ADRC

摘要

The control method for the velocity servo system for brushless DC motor was studied. A controller was developed based on ADRC. Simulation results were given at different conditionsincluding without load, parameters of motor changed with time and load changed with time, compared with PID., the controller based on ADRC ensures the excellent feature of stability and dynamic, and very good robustness under disturbance and parameters changed. AbstractDC motor is studied. A controller is proposed based on ADRC. Simulation results are given at different conditions including no load, motor parameters changed with time and load disturb, comparing with PID, the controller based on ADRC ensures excellent feature of stability and dynamic, and very good robustness under disturbance and parameters changed.
