Design on LADRC of shipboard antenna servo system [PDF]
Proceedings of the 2016 3rd International Conference on Materials Engineering, Manufacturing Technology and Control, 2016 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
