摘要
在空间交会状态模型的基础上,通过分析航天器的轨道动力学方程,给出了空间最省燃料交会轨迹和空间最优交会轨迹跟踪控制问题的数学描述。基于线性系统的特征结构配置和模型参考方法,提出了一种空间最优交会轨迹跟踪控制的参数化方法。应用该方法设计了系统的反馈镇定控制器和前馈跟踪控制器。仿真结果表明提出的控制方案是行之有效的。
According to the analysis of spacecraft orbital dynamics, the mathematic description of the trajectory of space rendezvous with the least fuel and the optimal trajectory tracking control problem is formulated based on the state space model of space rendezvous. A parametric approach is proposed for the optimal trajectory tracking control problem of space rendezvous by using the eigenstructure assignment and the model reference method of linear systems. A feedback stabilizing controller and a feedforward tracking controller are built. The simulation results show the effectiveness of the proposed method.
