基于最优控制的舵鳍联合减摇性能指标函数的分析研究

The method of choosing performance index for rudder/fin joint roll stabilization based on optical control

针对船舶舵鳍联合减摇控制中如何调整控制参数适应外部海况变化的问题,基于最优控制理论,对船舶运动的三自由度模型设计了舵鳍联合减摇最优控制器,重点研究了如何选择性能指标函数的问题,并通过数字仿真得到了权矩阵参数影响控制器减摇性能的规律。

In sight of how adjust control parameters facing the variation of waves, the optical rudder and fin joint controller for ship roll stabilization is designed based on the optical control theory. How to choose weighting matrices in performance index for designing controller is mainly studied, and the law of variation of weighting matrices about the performance of roll stabilization controller is gained.
