1.前言模型化问题是分析挠性结构人造卫星姿态运动必不可少的问题,关于这一问题,从1960年代后期到70年代前期进行了许多研究。关于模型化和表达的方法,运动方程的推导和模态分析,MODI,Williams,藤井等人已进行了全面综述。在这之前 Likins 和 Hughes 的概论性文章得到广泛应用。最近十余年的时间里,
1. Introduction Modeling is an indispensable problem in the analysis of attitude movements of flexible structures in satellites. Many studies have been conducted on this issue from the late 1960s to the early 1970s. Methods of modeling and expression, derivation of motion equations, and modal analysis, MODI, Williams, Fujii et al., Have been thoroughly reviewed. Prior to Likins and Hughes’s general article has been widely used. In the recent more than ten years,
