Research on Balance Control for Ship Roll Stability based on Transferring Liquid Among Water Cabins

摘要

this paper focuses on the ship roll balance control based on the ship roll dynamic model and special actuator. According to the ship dynamics model for roll stability and an actuator with the transferring liquid among Water cabins for ship,a control model for ship roll balance adjustment is built and also the control system is designed. And then,the ship balance performance and dynamic balance process based on the control model are investigated and analyzed with calculation and system simulation. In order to validate the system model built in the paper reasonable,a real case of ship is involved. Two kinds typical cases are employed so as to analysis the control performance. The research result shows it is significant to instruct and control the adjustment process of ship roll balance based on the control model. It can be applied to improve the ship safety and decrease the risk when the ship roll balance is damaged.
