基于遗传算法的终端区航迹优化方法

Optimization method of trajectories in the terminal area based on genetic algorithm

为了对终端区的航迹进行优化设计,以数学中的最优化理论为基础并借助遗传算法,根据设计所追求的性能目标建立了目标函数;在满足给定的约束条件下,寻求最优的设计方案,构建了科学的终端区航迹。仿真结果表明,所设计的方法有效地解决了终端区飞行航迹存在的飞行冲突和限制区避让等问题,保证了飞机在终端区飞行的安全性和经济性。

In order to optimally design the trajectory of the terminal area,the Genetic Algorithm(GA)which is based on the mathematical optimization theory is used to establish the objective function according to the design target,and the scientific terminal area trajectory is built by looking for the optimal design under the given constraint conditions.The simulation results show that the designed method effectively solves the problems of flight conflicts and avoidance in restricted areas etc.Thus the flight safety and economical efficiency are guaranteed.
