Abstract:

This paper proposed a sliding mode cooperative terminal guidance law to solve the problem of cooperative attack of the leader-follower missiles against a maneuvering target. The sliding mode surface was designed by taking the difference of the distance between the leader and the follower and its differentiation as the cooperative state variables, and the estimated time-to-go of the leader and the line of sight rate of the follower were introduced, so as to avoid the singularity problem. The target’s maneuvering acceleration was treated as a disturbance variable, and a switching control term utilizing its bounded nature was designed, ensuring the stability of the system and enhancing the robustness of the guidance law. Finally, digital simulations were conducted with three conditions. The results show that the guidance law proposed in this paper can achieve cooperative guidance.

Key words: cooperative guidance, sliding mode guidance law, leader-follower structure, maneuvering target, tacical missiles

摘要:

针对领弹-从弹架构战术导弹攻击机动目标的协同性问题,提出了一种滑模协同末制导律。以领弹和从弹的弹目距离差及其微分为协同状态变量设计滑模面,并引入领弹的剩余飞行时间估计值和从弹的视线角速率,避免了奇异性问题;将目标机动加速度视为干扰量,利用其有界性设计切换控制项,保证了系统的稳定性,增强了制导律的鲁棒性;在3种工况下进行了数学仿真,仿真结果表明提出的制导律满足协同制导要求。
