Abstract

自主水下机器人(AUV)与移动对接平台之间的实时路径规划,是AUV与移动对接平台进行自主对接的使能技术之一。针对复杂动态环境下AUV与水下移动平台对接的实时性和终端姿态需求,研究了一种基于混合整数线性规划(Mixed Integer Linear Programming,MILP)的AUV与水下移动平台对接的实时路径规划方法。利用对障碍物约束、AUV本体约束进行相应的分析和线性化,根据多个对接阶段的需求设计了距离收敛、时间最优和姿态最优等不同的目标优化函数,建立了移动对接目标函数,形成相应的多约束线性规划模型,实现对AUV加速度优化,得到满足所有约束且目标函数最优的实时优化路径。最后,在充分考虑AUV实际的动力学模型下的仿真实验分析,验证了此方法的有效性。

Other Abstract

The real-time path planning between AUV and mobile docking platform is one of the enabling technologies for autonomous docking between AUV and mobile docking platform. Aiming at the real-time and terminal attitude requirements of AUV docking with underwater mobile platform in complex dynamic environment, a real-time path planning method for AUV docking with underwater mobile platform based on mixed integer linear programming is studied. The obstacle constraints and AUV body constraints are analyzed and linearized. According to the requirements of multiple docking stages, different objective optimization functions, such as distance convergence, time optimization and attitude optimization, are designed. The objective function of mobile docking is established. The corresponding multi-constraint linear programming model is formed to optimize the AUV acceleration, and the real-time optimization path with all constraints and the objective function is obtained. Finally, the effectiveness of this method is verified by considering the simulation experiment under the actual dynamic model of AUV.
