中文摘要

      在新一代空中交通管理自动化系统实施方案中, 航迹规划模块在基于航迹的航空器运行过程中扮演着重要角色. 为了在大流量、高密度和小间隔条件下获取多航空器无冲突轨迹, 针对不同的航路空间分布结构, 基于航路冲突点保护区竞争机制, 构建了空域多航空器极大代数耦合模型和多航空器冲突预调配模型, 根据管制间隔约束建立了模型输入、状态和输出之间的约束关系. 采用调整航空器过冲突点时刻和初始放行时刻两种策略, 提出了一种多航空器轨迹规划优化模型. 算例分析表明, 所提出的多航空器轨迹规划模型可行有效.

英文摘要

      The trajectory planning module plays an important role in the new generation air traffic management automation system. For the planning of multiple aircraft conflict-free strategic trajectories under the condition of great traffic flow, high density, and small separation, the multi-aircraft max-algebra coupled model and conflict pre-deployment model are proposed based on competition mechanism as well as space distribution structure of air routes. The relationship between input variable, state variable and output variable is established according to the air traffic control separation constraints. The trajectory optimization model is formulated by adjusting the time of aircraft arrival and departure. Besides, the simulation results demonstrated the optimization model proposed in this paper is effective and feasible.
