N体航天器姿态运动的动态-测量系统建模

摘要

模型化处理是航天器测控工程的重要技术之一。以航天器姿态运动为研究对象，采用动力学分析的方法，建立带可扩展结构多体航天器姿态运动的动态-测量系统模型，并给出几种典型形式的线性、离散化模型简化方法，同时指出相关模型在航天器动力系统仿真和控制工程中的应用。%Modelling analysis technique is one of the important means in processing spaceflight mission. A series of dynamicmeasurement system models are built for the study of the attitude motion of a N-body spacecraft. These models are deduced with some typical methods of theoretical analysis and dynamic description, and are simplified into linearized discrete equations. Some valuable applications of the models are presented.
