摘要
本文从导弹控制工程的实际问题出发,运用奇异最优控制的基本概念,阐明快速控制奇异状态等价线性最优控制原理。 通过奇异最优调节器的设计,解决了导弹Bang-Bang Control(简称BBC)进入奇异区必须转换所带来的设计困难。快速控制与奇异最优控制相结合——双模控制体制,降低了系统灵敏度,极大地提高了系统鲁棒性,并具有优良工程特性,为导弹控制系统设计提供了一个新方法。 通过CSCAD仿真计算,获得了满意的工程控制效果。
Based on the theory of singular optimal control, the equivalene of the singular state of high speed control and linear optimal control is studied for the practical problems-of missile control engineering.This paper has solved a difficult design problem of selecting of required imperative transform when the missile Bang-Bang control (in abbreviation BBC) is used in the singular region. This new design method of combining singular optimal control with high speed control-two-mode control will reduce the sensitivity and improve the robustnest of the system.System simulations of this method by means of CSCAD give satisfactory results.
