最优飞行参考轨迹的线性规划算法与仿真

结合飞机地形跟随的实际,通过引入松弛变量,剩余变量和人工变量,构造辅助目标函数,以及应用换基运算,对线性规划问题进行了必要的简化,使参考轨迹的计算更简便。航迹角修正法的采用,进一步修正了规划出的飞行轨迹,从而获得了理想的飞行参考轨迹。最后,以各种典型地形为例对规划出的最优飞行参考轨迹进行了数字仿真,其结果符合地形跟随时最优飞行参考轨迹的要求。

Linear Programming Algorithm and Simulation of Optimized Reference Flight Path

According to the fact of fighter following terrain, flabby variable, remnant variable and artificial variable are introduced to form auxiliary object function, and in addition by applying operation of exchanging radix, the question of linear programming is necessarily simplified so as to make the calculation simpler. After adopting the correcting method of flight path angle, flight path planned is further modified and ideal reference flight path is obtained. Finally, as to the optimized flight path planned, numeral simulation are carried out by using various typical terrain, and the results accord with the requirements of optimized reference path in terrain following system.
