摘要
针对动态多目标围捕,提出了一种复杂环境下协同自组织多目标围捕方法.首先设计了多目标在复杂环境下的运动模型,然后通过对生物群体围捕行为的研究,构建了多目标简化虚拟受力模型.基于此受力模型和提出的动态多目标自组织任务分配算法,提出了群机器人协同自组织动态多目标围捕算法,这两个算法只需多目标和个体两最近邻位置信息以及个体面向多目标中心方向的两最近邻任务信息,计算简单高效,易于实现.接着获得了系统稳定时参数的设置范围.由仿真可知,所提的方法具有较好的灵活性、可扩展性和鲁棒性.最后给出了所提方法相较于其它方法的优势.
A self-organizing cooperative multi-target hunting method in complex environments is proposed for dynamic multi-target hunting. Firstly, the motion models of multi-target in complex environments are designed. Then, the multitarget simplified virtual-force model is constructed by researching the surrounding behavior of biological communities.Based on this force model and a proposed dynamic multi-target self-organizing task assignment algorithm, a cooperative self-organizing dynamic multi-target hunting algorithm by swarm robots is proposed. These two algorithms only need two kinds of information. One is the position information of multi-target and each robot’s two nearest neighbors, the other is the task information of each robot’s two nearest neighbors to the direction facing the multi-target center. Therefore, the new method is simple, efficient, and easy to implement. Then the parameter ranges for the stability of the system are given.Simulations results show that the proposed method has good flexibility, scalability, and robustness. Finally, the advantages of the proposed method over other methods are given.
