| 摘 要： | 再入飞行器采用变质心控制不但可以保持较好的气动外形,还可以降低能量消耗增大载荷能力,但该控制对气动力依赖较强,在气动力不足时需要借助其它控制系统来实现精确控制要求。文章研究了全空域飞行情况下变质心/RCS复合控制策略。通过对控制受限情况下变质心控制系统力矩配平和闭环响应快速性能的分析,将变质心控制的可行性转化为重压心距不等式组解的存在性,并基于此工程估算方法给出从变质心控制切换为RCS控制的复合控制策略。最后,通过对某再入飞行器一条典型机动弹道的仿真实验,验证了复合控制策略的有效性。

| Abstract: | Aim.The introduction of the full paper reviews a number of papers in the open literature and then proposes what we believe to be a new control strategy,which is explained in sections 1 and 2.Section 1 gives and simplifies the dynamics model of a reentry flight vehicle with both moving centroid control system and reaction control system(RCS);eqs.(3) and(4) are worth paying special attention to.Section 2 proposes our moving centroid/RCS control strategy;its core is that we analyze the trimming capability and ... |
