中文摘要: 实时4D航迹预测是新一代空中交通管理系统信息共享和协同决策的核心技术。精确的4D航迹能够保证空中交通安全的基础上充分灵活地利用空域和提高容量,并有效地探测和解决冲突。本课题在考虑空域内飞行流量、重要气象条件和航空器性能等信息的基础上提出了基于航空器意图信息共享的实时4D航迹预测方法。该方法采用航空器意图描述语言AIDL(Aircraft Intent Description Language)生成实时和精确的4D航迹,重点解决基于AIDL的适合于航迹计算的状态空间模型中参数的设置、微分方程的建立,以及考虑环境的变化、状态变化、操作冗余度、航空器意图等信息约束下航空器真实4D航迹的预测技术。本课题主要研究内容为:①航空器意图信息的处理方法;②建立基于意图信息共享的航空飞行器运动状态模型;③研究基于AIDL 的4D 航迹预测算法;④研究基于AIDL的4D实时航迹的冲突探测与解决方法。

英文摘要: Real-time 4D trajectory prediction is a key technology of the next generation air traffic management system for information share and collaborative decision. The project proposes an approach of aircraft 4D trajectory prediction based on aircraft intension information. This proposed approach adopts the Air Intent Description Language (AIDL) to generate precise real-time 4D trajectory and make full and flexible use of airspace, increase capacity and effectively detect and resolve conflicts without compromising with safety. This research topic, which takes into consideration such information as air traffic flow in specific airspace, weather information, aircraft performance, focuses on establishing the differential equation of state-space model and a set of their parameters, provides a real 4D trajectory with consideration of environment, pilot’s command, flight plan, performance etc.. The main content of the research includes: (1) the processing of aircraft intention information; (2) establishing the dynamic state model of aircraft based on aircraft intention information; (3) studying the AIDL-based 4D trajectory algorithm; (4) studying the AIDL-based conflict resolution algorithm.
