Research on active fin stabilizer at low speed and its application to ship roll stabilization

Fin stabilizers are often used at high speed of ship, however they also can produce effective lift through pitching actively at low speed. The lift model of fin stabilizer at low forward speed is proposed based on the fluid changing on fin stabilizer´s surface. Then the lift model is applied to the ship roll stabilization system. From simulation data, it can be seen that the roll of ship is reduced effectively by using fin stabilizer at low speed.
