【摘要】：复杂低空空域环境下多飞行器冲突解脱方法可以有效地提供冲突解脱策略,实时规划飞行器四维航迹,避免飞行器之间发生危险接近事故或者碰撞,从而保障空域运行安全。然而,随着飞行器数目的不断增长,冲突解脱面临"维数灾难",导致问题具有高维度、强耦合等难点。因此,传统的优化方案难以得到令人满意的方案。为了提高冲突解脱效率,保障运行安全,基于满意博弈论方法,考虑低空飞行器运动特点,构建冲突解脱模型,设计冲突解脱方法。飞行器主要采用改变航向角的策略。通过基于条件概率的方法来建立"社会关系",即当前飞机所做的决策对其他飞机产生的影响。每个飞行器在决策时,都会受到优先级比自己高的决策者的影响。基于满意博弈论的冲突解脱方法不仅可以有效地解决当前飞行器的冲突问题,而且兼顾探测范围内的其他飞行器,避免当前解脱策略导致与其他飞行器冲突,实现整体最优化。最后,通过在极端典型飞行冲突场景中实验验证表明,基于满意博弈论的冲突解脱方法可以实时高效实现大规模飞行器的冲突解脱,保障飞行安全且控制经济成本。
[Abstract]:In complex low-altitude airspace environment, multi-vehicle conflict resolution method can effectively provide conflict resolution strategy, real-time planning of aircraft four-dimensional track, to avoid dangerous proximity accidents or collisions between aircraft, so as to ensure the safety of airspace operation. However, with the increasing number of aircraft, conflict resolution is faced with "dimension disaster", which leads to the difficulties of high dimension and strong coupling. Therefore, the traditional optimization scheme is difficult to obtain satisfactory scheme. In order to improve the efficiency of conflict resolution and ensure the safety of operation, based on the satisfactory game theory method, considering the motion characteristics of low-altitude aircraft, the conflict resolution model is constructed and the conflict resolution method is designed. The aircraft mainly adopts the strategy of changing the heading angle. The method based on conditional probability is used to establish "social relations", that is, the influence of the decision made by the current aircraft on other aircraft. Each aircraft is influenced by decision makers with higher priorities when making decisions. The conflict resolution method based on satisfactory game theory can not only effectively solve the conflict problem of the current aircraft, but also take into account the other aircraft in the range of detection, avoid the conflict between the current strategy and other aircraft, and realize the overall optimization. Finally, the experimental results in extremely typical flight conflict scenarios show that the conflict resolution method based on satisfactory game theory can effectively and real-time achieve the conflict resolution of large-scale aircraft, ensure flight safety and control economic costs.
