摘　　要：讨论了无限元方法￣［１］与相同子结构串分析￣［２］的一致性，综合文［１］和［２］得到一种通用算法，依据文［３］尚可应用于ＬＱ控制问题，且提出一种直接求出转移矩阵的算法，具有简便和较高精度的优点．An agreement of the infinite element method and the analytical method for the chain of identical substructures is discussed in this paper.Ageneral solving program isgiven,which is based on reference[1]and[2]and can be applied to LQ control problems。Moreover,in this paper is the translative metrix X is solved directly by iderative method,which is very simple and accurate。

关 键 词：无限元方法 子结构串 转移矩阵 算法
