摘要
为研究海流干扰和水下碍航物影响下欠驱动圆碟形水下滑翔机集群的三维路径规划问题。本文根据圆碟形水下滑翔机的设备配置和工作特点,建立了相应的能量消耗模型。提出了一种基于全局与局部双层协调的三维路径规划体系,采用最小一致偏差法完成了能耗最优目标下多圆碟形水下滑翔机的全局路径规划。根据避碰原则预测出全局路径中存在的航行危险碰撞区域,基于人工势场法进行局部路径规划,避免了滑翔机与碍航物以及不同优先级的滑翔机之间发生碰撞。仿真结果验证了所提基于双层协调体系的多圆碟形水下滑翔机三维路径规划方法的有效性。
The purpose of this work is to study the three-dimensional path planning problem of multiple under-actuated saucer-type autonomous underwater gliders(AUGs)under the influence of ocean currents and underwater obstructions.First,a corresponding energy consumption model is established in accordance with the equipment configuration and working characteristics of saucer-type AUGs.Then,a three-dimensional path planning system based on global and local double-layer coordination is proposed.This system uses the biased min-consensus method to complete global path planning for multiple saucer-type AUGs with an energy consumption-optimal goal.Finally,the navigation dangerous collision area in the global path is predicted on the basis of the collision avoidance principle,and local path planning is performed in accordance with the artificial potential field method to avoid collision among AUGs with different priorities and underwater obstructions.Simulation results verify the effectiveness of the proposed three-dimensional path-planning method for multiple AUGs based on the double-layer coordination system.
