Finite Time Output Feedback Control for Ship Dynamic Positioning Assisted Mooring Positioning System with Disturbances

다국어 초록 (Multilingual Abstract)

This paper investigates finite-time output feedback control for ship dynamic positioning assisted mooring system with external disturbances and without velocity measurement. Firstly, a finite-time observer is designed to estimate the velocity of the positioning ship and the external disturbances. Secondly, based on the proposed observer, a finite-time control law is introduced to bring the ship to the desired position and heading. Furthermore, the stability of the overall closed-loop system is proved by using matrix inequality, homogeneous and Lyapunov stability theory. Finally, the effectiveness of the proposed positioning control is verified by numerical simulations.
