ADRC-based Ship-track Control and its Application to Traffic Safety Evaluation in Harbor Fairway

摘要

This paper investigates the control design of a novel ship-track controller, i.e., an active-disturbance-rejection-control (ADRC)-based ship-track autopilot, and its application to the traffic safety evaluation in harbor fairway. Firstly, a robust adaptive autopilot for ship track control is developed based on ADRC, which is a model-free controller and performs with minor control energy, strong robustness and easy implementation. Then, a new ship traffic safety evaluation methodology is proposed, where an impersonal and advising strategy of ship safe maneuvering action in the investigated fairway can be further achieved. The comparing simulation results demonstrate the effectiveness of the proposed method.
