摘要
针对空空导弹协同攻击高速机动目标问题,提出一种带有攻击时间一致的多弹协同制导律。首先,在纵向平面内建立各导弹与目标交战几何模型,分析视线径向、法向制导律和速度法向加速度之间关系。然后,设计固定时间协同控制律,并利用自适应律和积分滑模算法在视线方向动力学方程基础上建立攻击时间约束的鲁棒协同制导律,保证多枚导弹同时击中机动目标。通过数值仿真可得,协同时间与脱靶量差异分别为0.001 s和0.01 m,最终结果验证了固定时间协同制导律的有效性与合理性。
For the problem of air-to-air missile cooperative attack on high-speed maneuvering target,a multi-missile cooperative guidance law with consistent attack time is proposed.Firstly,the geometric model of engagement between each missile and target is established in the longitudinal plane,and the relationship between the radial and normal guidance laws of line of sight and the normal acceleration of velocity is analyzed.Then,the fixed time cooperative control law is designed,and based on the line of sight dynamic equation,the robust cooperative guidance law with attack-time constraint is established by using adaptive law and integral sliding mode algorithm to ensure that multiple missiles hit the maneuvering target at the same time.Through numerical simulation,the difference of cooperative time and miss distances are 0.001 s and 0.01 m respectively.The final results verify the effectiveness and rationality of the fixed-time cooperative guidance law.
