摘　　要：通过引入松驰变量、剩余变量和人工变量,构造辅助目标函数Z1,以及应用换基运算,使线性规划问题得以简化.对采集的地形数据预处理和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,对多种典型的地形规划出的最优飞行轨迹进行了数字仿真,其结果符合地形跟随时最优参考飞行轨迹的要求.First, by introducing flabby variable, remnant variable and artificial variable to form auxiliary object function Z1, and in addition applying operation of exchanging radix, the question of linearity planning is simplified; then, after pretreating the terrain data collected and adopting the correcting method of flight path angle, flight track planned is further modified and ideal reference track is obtained; last, as to the optimal flight tracks planned according to a variety of typical terrain, numeral simulation are carried out, the results accord with the requirements of optimal reference track in terrain following system.
