摘　　要：根据势流理论对船舶横摇运动波浪增阻进行分析,给出了模型解析表达式.利用水动力计算软件AQWA对船舶横摇运动产生的波浪增阻进行计算,通过回归分析方法确定了模型中的未知参数.基于对横摇运动姿态与波浪增阻的具体时域关系的分析,设计了带有波浪增阻优化的船舶横摇广义预测控制器.最后在不同海况下与常规减摇控制系统进行模拟比较,验证了该方法的有效性.该方法可为航速损失最小的新型减摇鳍开发提供理论依据,具有较好的应用价值.An added resistance model was presented after added resistance of ship roll motion was analyzed by potential flow theory.The added resistance induced by ship roll motion was calculated with hydrodynamic computation software AQWA and the model was modified by regression analysis method.The generalized predictive controller with optimum added resistance was designed based on the relationship of roll motion attitude and added resistance in time domain.Finally,the validity of this approach was proved by comparing with original roll stabilization control system in different sea conditions.This method is useful in developing the ship fin stabilizers with minimum speed loss.
