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 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.
