AGREEMENT OF THE INFINITE ELEMENT METHOD AND THE ANALYTICAL METHOD FOR CHAIN OF IDENTICAL SUBSTKUCTURES AND THE SOLUTION OF TRANSLATIVE MATRIX

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 reference1and2and 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。
