摘要
在飞机冲突避免和解脱问题中,为避免发生各种可能的冲突,所有飞机在飞行时彼此之间的距离必须要大于给定的最小安全间隔标准。针对同一空域中自由飞行的有限架飞机之间的冲突问题,提出一种基于速度和航向角变化两种策略相结合的混合整数非线性规划(MINLP)模型,以实现彼此的分离。算例仿真方面通过与集中于一种策略的冲突解脱模型进行比较,验证所提模型的有效性,并且其结果显示MINLP模型不仅可以利用全局优化软件在较短时间内为每架飞机提供一个最优解决方案,而且还能有效提高飞机在飞行过程中的安全性。
In the problem of aircraft conflict avoidance and resolution,all aircraft must be separated from each other by a distance greater than a given minimal safety separation during their flights to avoid various possible conflicts. In this paper,a Mixed Integer Nonlinear Programming( MINLP)model based on the maneuvers of velocity and heading angle changes is proposed for resolving the conflict between the limited aircraft flying freely in the same airspace to achieve the separation. The performance of the proposed model is verified by comparing with the conflict resolution models with only one maneuver. The illustration shows that the MINLP model provides an optimal solution for each aircraft in a short time by using global optimization software and improves effectively the safety of aircraft flights.
