摘要
在卫星轨迹控制系统的状态空间模型的基础上,通过分析卫星的轨道动力学方程,给出卫星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理论提出一种卫星轨迹跟踪控制的参数化方法,设计系统的反馈镇定控制器和前馈跟踪控制器。分别进行卫星悬停和绕飞两种指令下的仿真。仿真结果表明,提出的控制方案是行之有效的。
According to the analysis of satellite orbit dynamics, the mathematic description of the trajectory tracking control problem is formulated based on the state space representation of trajectory tracking control systems. A parametric approach is proposed for the satellite trajectory tracking problem by using the eigenstructure assignment theory and the model reference theory of linear systems. A feedback stabilizing controller and a feed-forward tracking controller are built. The designed controllers are applied to the satellite control system and simulation results are given under the hovering over and flying around command signals, which show the effect of the proposed method.
