A VARIABLE STRUCTURE GUIDANCE LAW BASED ON RELATIVE VELOCITY DEFLECTION ANGLE

本文研究了一种基于相对速度偏角的导引律。首先在相对运动学的基础上建立了归一化的导弹—目标的运动学模型 ,然后利用变结构控制理论设计了导引律。该导引律简便易行 ,仿真表明了该导引律能快速地消除相对速度偏角 ,实现小的脱靶量。

This paper studies a new guidance law based on the relative velocity deflection angle.The unitary missile target kinematics model is established based on the relative kinematics firstly.Then the guidance law is designed using variable structure system theory.This law can be carried out easily.The simulation shows that this law can eliminate the relative velocity deflection angle quickly and achieve little miss distance.
