3) free flight
自由飞行
1.
Conflict resolution in free flight with linear programming;
自由飞行中冲突解脱的线性规划法
2.
In the condition of free flight, in order to ensure the distance of two aircrafts could not less than a given safety distance, the Pontryagin minimum principle(PMP) of optimal control theory and inner-point restriction condition were introduced to study the conflict resolution problem of free flight aircrafts, in which control vectors were restricted.
在自由飞行中,为了保证任何两架飞机之间的距离不能小于给定的安全间隔,采用内点约束条件和最优控制中的庞特里亚金极小值原理,研究了自由飞行中飞机的控制向量受约束时的平面冲突解脱问题,考虑了只改变速度大小和只改变速度方向的解脱策略。
