摘要:针对飞行速度快速时变的便携式反坦克导弹制导控制问题,应用最优控制原理,提出了一种考虑导弹速度快速变化的改进弹道成型制导律。采用超前滞后环节进行时变过载自动驾驶仪设计;基于最优控制理论推导了广义弹道成型制导律和扩展弹道成型制导律,针对便携式导弹速度快速时变的特性,设计了包含时变速度信息的弹道成型制导律,并结合工程实际讨论了参数选择方法;最后进行了仿真对比和验证。仿真结果表明,该文提出的包含时变速度信息的弹道成型制导律能够满足武器系统的近距击顶作战需求,同时能够满足导弹系统的着角、攻角、框架角、过载等约束。

Abstract:Aiming at the guidance and control problem of the portable anti-tank missile with fast-varying velocity,an improved trajectory shaping guidance law(TSG)taking into account varying velocity was proposed based on the optimal control theory.The lead-lag controller was designed for the acceleration autopilot of the anti-tank missile.According to the optimal control theory,the generalized TSG and extended TSG were deduced.The improved TSG including the information of the fast varying velocity was designed,and the rule of parameter selection for the improved TSG was discussed.Simulation results show that the improved TSG proposed in this paper can make the missile attack the target from the top in short rang and satisfy the system requirements,as well as the impact angle,the attack angle,frame angle and acceleration constraints.

Key words:portable anti-tank missile;impact angle;generalized trajectory shaping guidance law;optimal control

便携式反坦克导弹因其轻便灵活、操作简单、可单兵或2-3人兵组携带、命中率高、威力大等优点,已经成为当今战场尤其是快速部署部队的重要武器。它以较大着角命中近距离处的坦克目标,实现近距击顶,增大毁伤效果。该导弹采用软发射技术,初始速度低,导弹发射后速度快速增加。如何在速度快速变化和导弹过载、攻角、导引头框架角等多重约束条件下进行便携式反坦克导弹近距击顶弹道设计,这是本文研究的重点。……
