摘要: 本文用预测制导的思想,具体研究运载火箭偏航通道的制导问题.阐述了摄动预测制导的基本原理,在有导航计算和有干扰测量两种情况下,推导了摄动预测制导的基本计算公式, 研究了预测制导的简化形式以及简化条件. 另外,本文还提出了预测制导的零控无偏状态的概念,以及向零控无偏状态导引的最优控制问题,推导了最优控制的闭合解.这些概念和结果有待进一步研究,仅供有关同志参考.Abstract: This paper deals with the yaw channel guidance of the launch vehicle in detail by means of the idea of predictive guidance. The basic principle of perturbative and predictive guidance are described. Under the conditions of both navigation computation and perturbative measurement the basic calculative formula of the perturbative and predictive guidance is derived and the simplified form of the predictive guidance and its requirements for the simplification are discussed. Besides, we also suggest the concept of zero control- and unbias states and the problem of optimal control guiding to the zero control and unbias states. A closeloop solution of optimal control was derived. The concept and results are to be researched further.
