Design on LADRC of shipboard antenna servo system

Since LADRC controller contains a disturbance estimation section and be able to eliminate the estimated disturbance timely, so the system of external disturbances hardly affect the output system, simulation results show that due to the real-time estimate LADRC changes and disturbances in real time compensation, so that the control system LADRC immunity than traditional PID control method can greatly improve the impact almost undisturbed.
