针对未加装减摇装置系统的船舶的横摇运动问题，本文提出由舵和翼舵构成2个相对独立的矢量控制面减横摇稳定控制系统，建立了矢量舵控制力矩和扭矩与舵角、翼舵角的m阶回归模型，给出了拟合精度。设计了系统μ-鲁棒控制器，本系统能量最小指标下设计了基于改进遗传算法的舵角/翼舵角智能协调决策器。仿真结果表明，在保证航向控制精度同时，矢量舵减横摇μ-鲁棒控制系统能有效减小横摇，降低系统能耗，且增强了抗系统参数摄动的鲁棒性。
For the roll motion problem of ships without anti-rolling device system, this paper proposes that the rudder and fin rudder constitute two relatively independent vector control plane roll stability control systems. The vector rudder control torque and the m-order regression model of torque, rudder angle and wing rudder angle are established accuracy. A system μ-robust controller is designed. The intelligent coordinator for rudder angle/wing rudder angle is designed based on the improved genetic algorithm. The simulation results show that the vector rudder is decelerated and the rudder is reduced. The rod control system can effectively reduce roll, reduce system energy consumption, and enhance the robustness against system parameter perturbation.
