从地形外形的采样数据设计飞机贴地飞行的期望航迹,然后由相应的最优控制器使飞机按此航迹飞行,这一地形跟随技术中的最优控制算法,日益得到重视和发展,并应用在综合地形跟随/回避技术中。 本文提出了采用圆弧样条计算期望航迹的方法,在几十种地形情况下进行了对比研究,证明是可行的。明显地减少了期望航迹计算的工作量,增加了系统实时计算的可能性。
From the terrain profile data, we design the expected flight path of the airplane and then use the corresponding optimal controller to fly the flight path. The terrain, which follows the optimal control algorithm in the technology, is gaining more and more attention and development. And applied in integrated terrain following / avoidance technology. In this paper, a method of calculating the desired track by circular arc spline is proposed. It is proved that it is feasible to do comparative study under dozens of topographic conditions. Obviously reduce the workload of the expected track calculation, increasing the possibility of real-time calculation of the system.
