Lift control system improved on single wing fin stabilizer at zero speed

It is different from conventional ship fin stabilizer that the lift of fin stabilizer is produced by initiative swing of movement mode of pitching and heaving at zero speed. For the fin stabilizer is belong to bigger inertia load, the reverse lift could be generated with the shorter braking time and the ship rolling would be acute and getting worse. So the lift limit element should be improved and lift limit is introduced. It is undoubtedly another development to introduce lift control to ship roll stabilization at zero forward speed. The simulation of anti rolling effect is researched at the different sea wave condition. And the anti rolling effects achieved over 55% respectively. It is proved that the designed system could be satisfied with the need of anti rolling ship at zero speed.
