摘要
主要介绍一种基于改进遗传算法的优化技术,利用遗传算法优越的全局搜索的能力,研究了飞行性能中的最快爬升性能。使用改进遗传算法对快升航迹和最佳爬升速度进行了寻优优化,对遗传算法优化快升的航迹和接近最快爬升方式的航迹进行了对比,表明,以遗传算法优化的快升航迹进行爬升,飞机可以最快的爬升到巡航高度。而且本算法以及程序具有一定的通用性适用于其它求最佳轨迹爬升的航迹优化。
An improved genetic algorithm optimization technique is introduced for optimal trajectories via simulation for optimal fastest climb trajectory based on the advantages of global optimization performance. The simulations between precise and approximate fast-climbing show that the method and program based on improved genetic algorithm are more exactly than traditional method, and the plane can climb up to the cruise height in the minimal time according to the optimal trajectory. This method and program are in general use and can be used to optimize minimal fuel-burned climb trajectory too.
