摘要
针对三维空间内多导弹对机动目标同时攻击的问题,提出一种具有自适应律的三维多导弹固定时间协同制导律。建立三维空间导弹-目标动力学模型,以弹目视线方向和其垂直方向设计制导律,可保证剩余飞行时间和法向速度在固定时间内完成一致性收敛。采用自适应律来跟踪机动目标运动参数策略,提高多导弹系统的稳定性与对机动目标的打击精度。改进多导弹系统收敛条件,所设计的制导律具备了对攻击时间的约束能力。向制导律中加入饱和函数,避免因符号函数带来的系统抖振。通过仿真实验验证所提固定时间协同制导律的有效性及对抗通信拓扑切换的鲁棒性。实验结果表明:相较于对比文献所设计的制导律具有系统快速收敛以及高精度。
An adaptive fixed-time cooperative guidance law is proposed for multiple missiles simultaneously attacking a maneuvering target in three-dimensional space.A 3-D missile-target dynamics model is established,and the adaptive guidance law are designed based on the line of sight(LOS)direction and its vertical direction.This ensures that the remaining flight time and normal velocity converge consistently within a fixed time.The adaptive guidance law are employed to track the motion parameters of maneuvering targets,thus enhancing the stability of multiple missile system and its strike accuracy against the maneuvering targets.The convergence conditions of the multiple missile system are improved,and the designed guidance law possess the capability to constrain the attack time.Saturated functions are introduced into the guidance law to avoid system oscillations caused by the sign function.The effectiveness of the proposed fixed-time cooperative guidance law and its robustness against communication topology switches are validated through simulation experiment.The experimental results indicate that,compared to the guidance law designed in the reference literatures,the proposed guidance law exhibit rapid system convergence and high accuracy.
