ObjectiveIn order to solve the problem of an underactuated ship responding slowly to heading changes during rudder roll stabilization (RRS) caused by fixed weight values in model predictive control (MPC), a RRS control method based on the finite time

This article presents a method to design a controller for active roll stabilization (ARS) with a disturbance feedforward control. To design the controller, a linear 1-DOF roll model is adopted. With the model, three feedback controllers, i.e., linear

The violent ship roll directly affects the safety of sea navigation and the ability to perform tasks, which makes ship anti-rolling become a research focus. Fin stabilizer is the most widely used and effective active anti-rolling device for ships. Ho

For improving the control system of traditional ship fin stabilizers, this paper presents a novel control system to solve the deviation of system feedback by using dynamic lift. However, the difficulty of lift feedback control is lift measurement tec

The motion control of a surface ship based on a four degrees of freedom (4-DoF) (surge, sway, roll, and yaw) maneuvering motion model is studied in this paper. A time-scale decomposition method is introduced to solve the path-following problem, imple

A ship navigating on the surface of the water may experience greater resistance, adversely affect-ing its speed and leading to energy loss. The added resistance of surface ships in both still water and waves are investigated, and the computation meth
