摘要: 针对地面目标精确打击及高效毁伤的需求,提出一种满足终端位置、落角及攻角约束的最优制导方法。利用比例导引项、落角约束项及加速度约束项保证终端命中多种约束条件,并且设计制导阶次实现全程加速度指令的优化分配,保证命中目标时的加速度指令收敛为小量。通过仿真计算验证了该制导方法能够满足精度、落角及攻角等终端约束条件,同时具有更好的加速度指令特性,有利于增强导弹的精确毁伤能力。

Abstract: A new optimal guidance law is presented to satisfy the terminal constraints for the precise strike and efficient damage to ground target. The proportional-navigation constraint, impact angle and acceleration constraints are used to achieve the terminal acceleration command convergence through the guidance-order adjustment. The simulation results show that the optimal guidance law can meet the terminal constraints, and the command performance and the attack effect are improved as well.

Key words: control and navigation technology of aerocraft, multiple constraints for penetrating, optimal guidance law, close-form solution, guidance characteristics
