基于路径约束的无人机进离场程序设计

Path Constraint based UAV Approach and Departure Program Design

在整个城市空中交通系统中,起降场终端区作为重要一环,其间的无人机进离场安全和效率至关重要。针对这一环,需要设计合理的空域结构和排序策略,以确保无人机进离场的安全和效率。从空域设计和排序策略等方面,考虑进离场路径约束,设计无人机进离场程序。首先建立无人机进离场空域模型,设计飞行程序;采用先到先服务排序策略,按计划排序策略和诚信原则排序策略进行仿真实验,并从延误时间和模型稳定性等方面分析,得到三种排序策略中先到先服务排序策略与模型匹配度最高。

In the whole urban air transportation system,the terminal area of the take off and landing site is an important link,during which the safety and efficiency of UAV approach and departure are crucial.For this link,a reasonable airspace structure and sequencing strategy need to be designed to ensure the safety and efficiency of UAV approach and departure.In this paper,we consider the approach and departure path constraints from the aspects of airspace design and sequencing strategy,and design the UAV approach and departure program.Firstly,the airspace model of UAV approach and departure is established,and the flight procedure is designed;the first come first served sequencing strategy,the sequencing strategy according to plan,and the honesty principle sequencing strategy are used to carry out simulation experiments and analyze the delay time and model stability to obtain the highest degree of matching between the first come first served sequencing strategy and the model among the three kinds of sequencing strategies.
