一种有限推力航天器交会轨道的鲁棒设计方法

基于C—W方程描述的二体相对运动模型，考虑利用范数有界方法刻画航天器交会过程中的参数不确定性，并结合控制推力受限的工程需要，提出了一种在不确定环境下有限推力航天器交会轨道的设计方法。通过构造Lyapunov函数，将此设计问题转化为一个具有线性矩阵不等式约束的凸优化问题，通过求解此问题即可设计出符合航天器交会要求的鲁棒状态反馈控制器。

A Robust Orbit Design Method for Thrust-Limited Spacecraft Rendezvous

Based on the relative motion dynamic model described by C-W equations,and by considering parameter uncertainties characterized by the norm-bounded method and the control input constraints in practice,a robust orbit design approach is proposed for the spacecraft rendezvous engineering.By introducing a Lyapunov function,the design problem is cast into a convex optimization problem subject to linear matrix inequalities.By solving this optimization problem,the robust controllers satisfying the requirements can ...
