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。
In this paper, we use the theory of predictive guidance to study the guidance problem of the launch vehicle’s yaw channel. The basic principles of perturbed predictive guidance are explained. Under the two situations of navigation calculation and interference measurement, the basic formulas of perturbed predictive guidance are deduced. The simplified form of predictive guidance and the simplified conditions are also studied. In addition, this paper also proposed the concept of predictive guidance “zero-control unbiased state” and the optimal control problem directed to the zero-control unbiased state, and deduced the closed solution of the optimal control. These concepts and results are for further study and are for reference only by the comrades concerned.
