| Abstract: | Active control of ship roll motion with proportional and derivative controller, linear quadratic regulator, generalized predictive control (GPC), and deadbeat predictive control, is studied by using a U-tube water tank. For the predictive control, system identification is applied to update the parameters of linear ship roll model with U-tube tank when the ship dynamics changes. Numerical simulations show that GPC has the best performance and the U-tube tank is effective in ship roll mitigation. |
