基于SNOPT优化的交互式航迹规划软件设计

Design of Interactive Trajectory Planning Software Based on SNOPT

借助SNOPT(Sparse Nonlinear OPTimizer)软件包可以编写判断飞行段与禁飞区相交的简易算法,如果直接把约束条件全部加入,可能会因为过于保守而得不到可行解。将已有判断与优化算法集成,使用MFC搭建操作界面,再利用GDI绘制飞行器的航行轨迹。根据仿真结果手动添加特定圆弧段与禁飞区相交的约束条件进行航迹修正,结果都可以直观地显示在图形窗口中,最终成果是一个人机交互良好的软件包。

Simplified path planning subject to no-fly zones can be obtained based on SNOPT(Sparse Nonlinear OPTimizer)software.However,when all these conditions are all considered,it may be too conservative to obtain feasible solution.This paper attempts to integrate the existing judgment and optimization algorithms in an interactive software package.The interface is established by using MFC and the trajectory of an aircraft is plotted by using GDI.The undesired trajectory can be modified through adding active constraints explicitly including specific circular arcs and no-fly zones.The purpose of this paper is design of interactive trajectory planning software.
