主辅拦截器协同制导方法研究

Study on Collaborative Guidance Control Method for Main and Auxiliary Interceptors

随着现代导弹技术的发展,导弹的突防能力越来越强,对导弹的防御难度也逐渐增大。为增强拦截器的杀伤力并降低成本,可利用主辅拦截器协同制导对目标进行拦截。建立了拦截器与目标的相对运动模型,通过对运动方程进行线性化分析,发现协同制导问题实质为具有终端时间限制条件的导引问题,该问题可转化为线性化系统的最优控制问题。利用最优控制中的极小值原理设计了时间协同制导律。仿真结果表明:该制导律可实现多枚拦截器在同一时刻拦截目标的协同制导要求。

With the development of modern missile technology,the penetration capability of missile has become increasingly strong,and the difficulty of missile defense is also gradually increased.In order to improve interceptor’s lethality and lower the cost,main and auxiliary interceptors can be used to intercept targets through collaborative guidance.The relative motion model of interceptor and target is established.Through the analysis of the linear equation motion,it is found that the collaborative guidance problem is,in essence,aguidance problem with time constraints.Therefore,the problem can be transformed into the linear optimal control problem.In this paper,the time collaborative guidance law is designed by using the optimal control minimum theory.The collaborative guidance simulation results show that this guidance law can achieve the requirements that multiple interceptors intercept targets at the same time through the collaborative guidance.
