基于改进LOS导航算法的智能船舶自动靠泊控制研究

    Intelligent Automatic Control of Ship Berthing with Improved LOS Guidance

    • 摘要: 针对智能船舶自动靠泊控制中航迹规划和轨迹跟踪的问题,提出一种基于改进视线导航(LOS)算法的自动靠泊方案。将LOS导航算法与线性自抗扰控制(LADRC)器结合,解决了靠泊过程中模型内部参数不确定性和外部时变扰动的问题。为了进一步解决自动靠泊转向过程中跟踪误差大的问题,在LOS算法中融合坐标补偿算法,改善了系统控制性能,加快了收敛速度。通过引入线性自抗扰控制器,增强了系统对外界时变扰动的抑制能力。仿真结果表明,LOS和坐标补偿融合算法具有良好的鲁棒性和显著的控制效果,为船舶自动靠泊控制提供了一种有效的技术手段。

       

      Abstract: The LOS guidance algorithm combined with a linear Active disturbance rejection controller is introduced into ship berthing control for the trajectory planning and tracking. This combination is good at dealing uncertainty of system parameters and time-varying disturbances. The algorithm for compensating ship coordinates is integrated into the LOG guidance control to improve the tracking accuracy in the process of ship turning and to accelerate the convergence process. The control design is simulated and good results are demonstrated.
