远距引导战斗机自动攻击控制律实现

Realization of Auto-Attacking Control Law for Long-Distance Guidance of Fighter Planes

针对现代战斗机向目标空域的远距引导过程,建立了战斗机与目标的三维相对运动数学模型,引入了战斗机自动攻击的概念,并将三维引导问题分解到水平和垂直两个面内分别进行研究;基于战斗机远距引导时间最短的要求以及最优控制的相关理论,以时间最短为目标分别设计了战斗机水平面和垂直面的远距引导律,在此基础上设计了远距引导战斗机自动攻击控制律;最后通过仿真比较,验证了时间最优引导法能有效应用于战斗机为实现自动攻击的远距引导。

Considering the long-distance guidance procedure of modem fighter planes flying to target airspace, the relative motion model of fighter plane and target was built up, and the auto-attack concept was introduced. The 3D guidance was decomposed into vertical aspect and horizontal aspect. Based on the requirement of the shortest guidance time and the theory of optimal control to long-distance guidance of fighter plane, the long-distance guidance law for horizontal and vertical track of fighter plane was designed taking the shortest guidance time as a goal. The auto-attack control law was also designed. At last a simulation example was given, whose results show that the optimum time guidance is an effective mode for the guidance of fighter plane.
