【摘要】 巡飞弹集群协同执行任务越来越成为现代化作战的发展方向。巡飞弹集群通过信息共享相互配合实现协同作战,对多类目标形成饱和攻击的态势,涌现出巨大的毁伤效能。本文以攻击区域信息未知的某敌方军事基地为作战背景,总结巡飞弹集群作战的特点,构建巡飞弹集群协同分布式作战体系。并对巡飞弹集群协同搜索、协同目标分配以及协同目标导引进行研究。主要的工作总结如下:首先,针对区域信息未知的情况,提出了基于改进蚁群算法的巡飞弹集群协同搜索算法。该算法运用蚁群理论中信息素反馈机制,控制巡飞弹集群自主协同搜索,并通过实验仿真验证了本文提出的搜索算法区域搜索覆盖率和目标搜索效率的可行性和高效性。其次,针对巡飞弹集群目标协同分配的问题,根据巡飞弹集群目标分配的特点,对传统合同网协议理论进行改进,省略任务招标环节,减小了招标过程所造成的巡飞弹间通信负担。另外,转变传统合同网协议的全局最优目标分配为局部最优目标分配。通过实验仿真验证了本文目标分配算法的可行性。最后,关于巡飞弹协同导引方面的问题,第一、针对运动目标提出基于滚动时域控制的导引律,把多约束的机动目标导引问题转化为连续的滚动时域内匀速直线运动目标的导引问题。第二、对巡飞弹落角约束进行研究,基于速度矢量三角形,得到巡飞弹视角与视线俯仰角的关系,进一步设计基于落角约束的比例导引律,研究不同落角约束下的巡飞弹飞行特性。第三、提出滑模变结构控制导引律,解决基于时间约束的巡飞弹协同导引问题。以上导引律均通过数值实验仿真验证了其可行性。更多还原

【Abstract】 Performing cooperative tasks of multiple loitering aerial vehicle(LAV)has increasingly become the trend of the modern combat.Through sharing information,the LAV cooperates with each other to achieve coordinated operations in swarms,and formes a situation of saturated attack on many types of targets,causing a great damage effect.In this paper,an enemy military based on whose information is unknown is used as a background,we summarized the characteristics of the multi-LAVs,and built a coordinated distributed combat system for LAV swarms.Meanwhile,we researched on the coordinated search,targets assignment,and guidance law of LAV swarms,and the main work is summarized as follows:Firstly,aiming at the situation that the regional information is unknown,a coordinated search algorithm of the LAV based on the improved ant colony algorithm was proposed.The algorithm uses the pheromone feedback mechanism in the ant colony theory to control the autonomous collaborative search of the LAV.The simulation results verified the feasibility and efficiency of the proposed algorithm.Secondly,aiming at the coordinated of targets assignment in LAV swarms,the traditional contract net protocol theory was improved,eliminating the task bidding process and avoiding the pressure caused by the bidding process according to the characteristics of LAV swarms.In addition,we changed the global optimal target allocation of the traditional contract network protocol into the local optimal target allocation.The feasibility of the target allocation algorithm in this paper was verified by simulation.Finally,on the issue of cooperative guidance of multi-LAVs,a guidance law based on receding horizon control was proposed for the maneuvering targets,and the problem of multiconstraints maneuvering target guidance was transformed into the problem of a continuous linear moving target guidance based on receding horizon;According to the velocity vector triangle,the relationship between the angle of view and the pitch angle of sight of the LAV was obtained,the proportional guidance law based on the attitude angle constraint was further designed to study the flight characteristics;the sliding-mode variable structure control guidance law was proposed to solve the coordinated guidance problem of multi-LAVs based on time constraints.The above guidance laws verify the feasibility through numerical simulation.更多还原
