基于混杂系统理论的无冲突4D航迹预测
Conflict-Free 4D Trajectory Prediction Based on Hybrid System Theory
摘要
Abstract
In order to increase airspace capacity, the hybrid system theory was used to build a state switch model of aircraft between different segments that is based on the aircraft aerodynamics models by setting three flight status including climb, decent, and level flight as well as seven parameters of height and speed during the process of aircraft trajectory strategic planning. Then, a state evolution model was also built for an aircraft with parameters such as aircraft weight, airspeed, altitude, and ground distance continuously changing during the same segment. In order to plan multi-aircraft trajectories, a conflict-free trajectory planning method was proposed by adjusting the aircraft arrival time and flight speed. The simulation of a case study shows that using the hybrid recursive method, the aircraft takeoff 4D trajectory with aircraft performance constraints can be obtained within 3 s, the two models proposed in this paper can reflect the aircraft horizontal and vertical trajectory profiles precisely, and the conflict-free trajectory planning method is effective.关键词
