基于李亚普诺夫最优反馈控制的中制导

Midcourse guidance based on Lyapunov optimal feedback control

基于李亚普诺夫最优反馈控制的2种实现方法,即时间最速下降法与空间最速下降法,提出了一种混合策略。应用于导弹中制导,获得了满意的结果,可以极大地缩短中制导飞行时间并大幅度地提高中制导末端速度。仿真结果表明,该方法有一定的工程应用参考价值。

Upon the quickest descent method and the steepest descent one in Lyapunov optimizing feedback control, a mixed strategy is proposed. By applying the strategy to midcourse guidance problem, satisfactory results are obtained. Simulation results show that the guidance time is greatly decreased and terminal velocity is largely increased. Potential applications of this approach in missile guidance is expected.
