摘要:

提出了一种可实现的离散时间最优末制导律,该制导律在导弹导引头获取的目标加速度信息的基础上,以时间最优为设计指标,可动态调整最优控制量,能够适应目标末端机动,并采用变周期算法以提高收敛速度。仿真结果表明,该制导律能够满足给定脱靶量要求,成功拦截目标。

Abstract:

An optimal terminal guidance law was proposed in this paper. It can be realized easily based on the information of target’s acceleration acquired by the missile’s radar. Optimal time is the guidance law’s index and control variable can be dynamic adjusted, so it can adapt target’s terminal move. Through changing periods, convergence rate is improved. Simulation results show that the guidance law can meet the need of given missing distance and intercept target successfully.
