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。
Model processing is one of the important technologies of spacecraft measurement and control engineering. Taking the attitude movement of the spacecraft as the research object, a dynamic-measurement system model of the attitude movement of the multi-body spacecraft with an expandable structure is established by the method of dynamic analysis. Several typical forms of linear and discretization model simplification methods are given. At the same time, the application of relevant models in the simulation and control of spacecraft power system is also pointed out.
