非对称机动能力多无人机智能协同攻防对抗 总被引:1,自引:0,他引:1
协同攻防对抗是未来军用无人机的重要作战场景。针对不同机动能力无人机群体间的攻防对抗问题,建立了多无人机协同攻防演化模型,基于多智能体强化学习理论,研究了多无人机协同攻防的自主决策方法,提出了基于执行-评判(Actor-Critic)算法的集中式评判和分布式执行的算法结构,保证算法稳定收敛的同时,提升执行效率。无人机的评判模块使用全局信息评价决策优劣引导策略学习,而执行时只需要依赖局部感知信息进行自主决策,提高了多机攻防对抗的效能。仿真结果表明,所提的多无人机强化学习方法具备较强的自进化属性,赋予了无人机一定智能,即稳定的自主学习能力,通过不断演化,能自主学习提升协同对抗的决策效能。 相似文献

Coordinated mission decision-making is one of the core steps to effectively exploit the capabilities of cooperative attack of multiple aircrafts. However, the situational assessment is an essential base to realize the mission decision-making. Therefore, in this paper, we develop a mission decision-making method of multi-aircraft cooperatively attacking multi-target based on situational assessment. We have studied the situational assessment mathematical model based on the Dempster-Shafer (D-S) evidence theory and the mission decision-making mathematical model based on the game theory. The proposed mission decision-making method of antagonized airfight is validated by some simulation examples of a swarm of unmanned combat aerial vehicles (UCAVs) that carry out the mission of the suppressing of enemy air defenses (SEAD). 相似文献

With the development of Unmanned Aerial Vehicle (UAV) system autonomy, network communication technology and group intelligence theory, mission execution in the form of a UAV swarm will be an important realization of future applications. Traditional single-UAV mission reliability modeling methods have been unable to meet the requirements of UAV swarm mission reliability modeling. Therefore, the UAV swarm mission reliability modeling and evaluation method is proposed. First, aimed at the interdependence among the multiple layers, a multi-layer network model of a UAV swarm is established. At the same time, based on the system having the following characteristics—using a mission chain to complete the mission and applying the connectivity of the mission network—the mission network model of a UAV swarm is established. Second, vulnerability and connectivity are selected as two indicators to reflect the reliability of the mission, and aimed at random attack and deliberate attack, vulnerability and connectivity evaluation methods are proposed. Finally, the validity and accuracy of the constructed model are verified through simulations, and the model and selected indicators can meet the reliability requirements of the UAV swarm mission. In this way, this study provides quantitative reference for UAV-swarm-related decision-making work and supports the development of UAV-swarm-related work. 相似文献

In this paper, a new mission model, called a multi-debris active removal mission with partial debris capture strategy, is proposed. The model assumes that a platform only captures part of the scheduled debris at a time and then releases these debris pieces to a disposal orbit. This process is then repeated until all of the scheduled debris is removed. A genetic algorithm with a multiparameter concatenated coding method is designed to optimize the plan of a multi-debris active removal mission wit... 相似文献

直升机海上搜救是航空应急救援体系中十分重要的组成部分,但搜救部门在执行相关任务时通常只能依靠已有经验对险情进行分析并制定处置方案,缺乏理论的指导以及工具的支撑。针对海上应急响应过程中从接收到遇险信息到开始执行海上搜救任务之前的阶段,提出一种海上搜救处置决策支持技术框架,在此基础上,研发民用直升机海上搜救遇险人员处置决策支持系统,并通过海上搜救典型任务进行验证。结果表明:该系统能够通过快速制定处置方案并输出评估结果,为实际执行海上搜救任务的机组人员提供处置决策支持建议,间接提高海上搜救效率。 相似文献

As multi-discipline coupling and components interference often affect the aircraft configuration decision-making and analysis during conceptual design process, this article presents an approach of multidimensional game theory based on aircraft components to deal with this problem. The idea is that the configuration decision-making process is regarded as the game for different disciplines and technologies, and the aircraft components are players. The payoff function with highest total gain means that according to the game protocols and multidimensional theory, the optimal aircraft configuration within the strategy set will be chosen. The decision-making model is applied to conceptual design process of the high altitude long endurance (HALE) unmanned aerial vehicle (UAV) based on the assessment of technological risk. The obtained optimum configuration is quite consistent with the current HALE UAV development trends. Thus, taking into account the coupling and interference factors, the multidimensional gaming model based on aircraft components will be an effective analysis method in the decision-making process of aircraft optimum configuration. 相似文献

随着智能化、网络化集群作战等理念和技术的兴起,精确制导武器越来越向智能化、协同化方向发展。多传感器协同探测能够针对不同的探测任务背景和作战需求,提升目标探测性能,还可以跨域整合多种探测平台。但是由于信息的不确定性等特点,使得多传感器数据直接融合可能造成决策困难。因此,在证据理论体系下对信息融合的有效性进行合理分析与度量是很有必要的。提出了一种基于Deng熵的证据理论分类融合算法,以熵减为主要思想,将证据进行分类融合。在决策过程中,将含有证据数最多的类别融合结果作为总体融合结果,避免高冲突证据的影响,提升融合结果的信息有效性。采用算例说明了所提方法不仅能够得到合理正确的结果,并且融合可靠性较高,便于决策与后续的信息处理。 相似文献

航空兵任务规划系统中飞机空对地攻击航线解算的准确性、航线生成质量和航线解算速度是衡量任务规划系统能力的重要指标。飞机空对地攻击航线设计是飞机航线规划中典型的多约束复杂机动,其在设计与使用过程中受到来自时间、空间及飞机本体的多维约束,对飞行动力学建模与航迹优化提出了较高的要求。本文利用面向对象的思想对飞机无侧滑动力学模型进行建模,通过航线机动动作拼接、分段优化的方式实现复杂机动过程的设计与优化,并进行仿真分析。结果表明:该航线优化设计能够实现飞机多约束航迹设计与规划功能,迭代优化算法具有较好的收敛性,可满足航空兵任务规划使用要求。 相似文献
