简介:本文研究了加速度目标最优线性二次制导问题。导弹状态分为运动学状态和弹体状态。这篇报告不仅论述了补偿加权(Penalty-weighted)而且研究了终端状态的约束情况。所得到的最优制导规律要求估计目标加速度,而这种估计是通过线性观测器得到的。给出了点质量导弹、一阶时间常数和二阶时间常数导弹的结果。
Summary: This paper investigates the optimal linear quadratic guidance problem for acceleration targets. Missile state is divided into kinematic state and projectile state. This report discusses not only Penalty-weighted but also constraints on the state of the terminal. The resulting optimal guidance law requires estimation of the target acceleration, which is obtained by a linear observer. The results of point mass missiles, first order time constants and second order time constant missiles are given.
