基于动态调速的定航线飞行冲突探测与解脱

Airline flying conflict survey and extrication based on dynamic velocity modulation

针对同一层空域下的定航线的两架或三架飞行器,提出一种动态调整飞行器飞行速度的方案以避免飞行冲突的发生。当飞行器进入调速区后动态检测各飞行器的位置及相互之间的距离,首先对飞行器和飞行器与航线交叉点之间的距离进行判断,依据判断的结论建立飞行器坐标系,并利用刻画各飞行器间的位置及其变化的一组偏微分方程和优化控制理论对飞行器的速度进行调节。仿真试验结果证明该调速方案是安全的。

A scheme for conflict resolution with dynamically changing the speeds of two or three aircrafts flying on the two air flows in the same flight height was proposed. The positions of the aircrafts and the distance between them were dynamically checked while the aircrafts entered the alert area, which was a circle plate around the intersection of the two air flows. The scheme computed the distance between the aircrafts and the intersection firstly. Then the coordinates were set up according to the distance computed on last step; therefore, the coordinates became the aircraft coordinates with small distance. The speeds were adjusted according to a set of partial differential equations and optimal control theory. The experimental results show that the scheme is safe.
