| 摘 要： | 基于最优控制理论二次性能最优的条件下推导最优导引律的解析解通常是困难的。该文基于二阶制导系统，利用许瓦兹不等式能很容易地推导出一种用解析形式表示的最优导引律。该导引律通过估算剩余飞行时间、测量导弹速度及其导数，能实现零脱靶拦截，且制导系统所需的机动能量与比例导引相比要小得多。

| Abstract: | It is difficult to obtain the closedform solutions of optimal navigation law on the basis of an optimal quadratic performance of the optimal control theory.In this paper,one kind of closedform solutions for optimal navigation law of 2order guidance system is derived by use of the Schwartz inequality.By estimating time to go,measuring missile velocity and its derivative the navigation law can yield zeromiss distance,and minimize the integral of the square of the command acceleration. |
