摘要: 为了实现欠驱动无人水面船舶(USV)的航迹跟踪和避碰功能,构建了基于模型预测控制的自主导航模型,其中包括航迹偏移、速度变化和规则遵从性作为评估函数,以及动态/静态导航障碍的船舶领域和机械特性限制作为约束条件。通过多组仿真实验验证了该模型在多船遭遇情况下以及存在动态和静态障碍物的复杂水域中对USV自主导航的有效性。仿真结果表明,所提出的模型能够在复杂水域下实现欠驱动USV自主导航。

Abstract: To achieve the track following and collision avoidance of underactuated unmanned surface vehicle (USV), autonomous navigation model based on model predictive control is established by including the track offset, speed variation and rule compliance as the evaluation functions and including the ship domain of dynamic/ static navigation obstacles and the mechanical characteristics limitation as constraints. The effectiveness of the model for autonomous navigation of USV in the situation of multi-ship encounters and in the complex waters with both dynamic and static obstructions is verified by several groups of simulation work. The simulation results show that the proposed model can realize the autonomous navigation of the underactuated USV under the complex waters.
