摘要 本文对月球着陆器最终下降段的控制方法进行了研究,提出了一种同时保证主推力与姿态控制力矩有界的方案,并从理论证明了制导与姿态控制系统的联合稳定性。本文的主要创新之处在于:提出了一种形式上更为简单的嵌套饱和函数形式的制导律,该制导律具有调节推力上界与着陆器的最大偏斜角,以及限制速度大小等优点;提出了一种具有饱和函数限制形式的姿态控制律,证明了力矩的有界性,并给出了力矩上界的具体估计方法;运用级联系统的相关理论严格证明了联合系统的全局渐近稳定性。文章最后用数值仿真验证了本文方案的可行性。 本文对月球着陆器最终下降段的控制方法进行了研究,提出了一种同时保证主推力与姿态控制力矩有界的方案,并从理论证明了制导与姿态控制系统的联合稳定性。本文的主要创新之处在于:提出了一种形式上更为简单的嵌套饱和函数形式的制导律,该制导律具有调节推力上界与着陆器的最大偏斜角,以及限制速度大小等优点;提出了一种具有饱和函数限制形式的姿态控制律,证明了力矩的有界性,并给出了力矩上界的具体估计方法;运用级联系统的相关理论严格证明了联合系统的全局渐近稳定性。文章最后用数值仿真验证了本文方案的可行性。
