| 摘 要： | 根据精确的虚拟目标比例导引系统数学模型,分析了系统的一个平衡状态,构造Lyapunov函数得出了进入该状态的充分条件。由此设计出的虚拟目标比例导引律,能保证导弹以给定的落角击中目标,并有效地避免了比例导引末端控制量发散的问题。通过调节虚拟目标变速运动的变速因子,既保证终端导弹速度方向满足落角限制,又有效地减小了脱靶量。仿真结果表明了设计方法的正确性。

| Abstract: | According to the exact model of Virtual Target's Proportional Navigation,a balance state of the system was discussed,and a sufficient condition of entering to the state was gained by constructing a Lyapunov function.Based on that,two virtual target's proportional navigation laws were designed,which can control the terminal azimuth of a missile,and which can also avoid the situation that the signal of control is too big at the end of propotional navigation.Finally,the simulation results are presented to show the correctness of the proposed method. |
