摘要: 针对未知环境下多无人机(unmanned aerial vehicles, UAV)协同搜索问题展开研究,通过网格化的环境规则描述,给出了UAV的运动规则及UAV系统的预测模型. 考虑实际战术需求,建立了满足UAV机动性能约束的区域再次进入数学模型,给出了最短再入路径的求解方法. 引入了“伸缩式”协同搜索机制,增加对未知环境的
适应性,同时设计了系统的全局信息库,从而充分利用UAV实时探测的环境信息,实施在线滚动规划. 通过仿真验证了方法的有效性.

关键词: 无人机, 未知环境, 协同搜索, 区域再入模型, 最短再入路径

Abstract:  This paper addresses a cooperative search problem where a team of unmanned aerial vehicles (UAVs) seeks to reduce uncertainty in an unknown environment. The gird-based representation of search environment is established, and a UAV dynamic model and a predictive model of UAV systems are presented.Taking into account the practical tactical requirements, an area re-enter model is formulated, considering some maneuverability constraints. The corresponding shortest re-enter path is formulated. We develop a cooperative search strategy based on “retractable” mechanism, which can enhance adaptability to unknown environments. We also propose a global information base to make full use of the real-time local environmental information
detected by the UAVs, and generate the search path on-line in a rolling style. Simulation results are presented to demonstrate the main feature of the proposed method.

Key words:  unmanned aerial vehicle (UAV), unknown environment, cooperative search, area re-enter model,
shortest re-enter path
