摘要/Abstract

摘要： 在末段高层拦截弹的主动段中制导中, 考虑主动段飞行中导弹的速度的变化, 满足末速度的角度约束, 同时要求使控制量尽可能小, 为了能够实现这些约束, 在指标函数中, 采用时变的控制量权重系数, 利用极小值原理, 伪控制量的办法, 得到了一种最优中制导律。仿真结果表明, 这种指标函数中加入可变控制量权重的办法, 在保证精度的同时, 可以有效地控制控制量的大小。

Abstract: Considering the change of the velocity of missile in the active section flight in the guidance of the active section of the terminal high altitude interceptor, the angle constraint of the final velocity was required to meet and the control amount was required as small as possible. To realize these constraints, in the index function, an optimal guidance law by adopting the time varying control weight coefficient was obtained, using the minimum principle, as well as pseudo control method. The simulation results showed that the method of adding variable weight in this index function can control the size of the control while guaranteeing the precision.

Key words: end high-level, angle constraint, active section, variable weight, optimal control, minimum principle
