摘要

本文研究了求解两个耦合模糊Sylvester矩阵方程的五种迭代方法。首先利用系数矩阵的广义逆表示两个耦合模糊Sylvester矩阵方程,然后应用层次辨识原理,利用分块矩阵内积(简称星形积)构造迭代解。提出了一种改进算法,用于求解第一耦合模糊Sylvester矩阵方程。并与第一种算法进行了比较,结果表明该算法具有较快的收敛性。同时,我们提出了两种最小二乘迭代算法,应用层次辨识原理求解两个耦合的模糊Sylvester矩阵方程。通过数值算例说明了所提出的方法。

Solving Two Coupled Fuzzy Sylvester Matrix Equations Using Iterative Least-squares Solutions
ABSTRACT In this paper, five iterative methods for solving two coupled fuzzy Sylvester matrix equations are considered. The two coupled fuzzy Sylvester matrix equations are expressed by using the generalized inverse of the coefficient matrix, then iterative solutions are constructed by applying the hierarchical identification principle and by using the block-matrix inner product (the star product for short). A proposed modification to this algorithm to solve the first coupled fuzzy Sylvester matrix equations is suggested. This proposed modification is compared with the first algorithm where our modification exhibits fast convergence behavior. Also, we suggested two least-squares iterative algorithm by applying a hierarchical identification principle to solve the two coupled fuzzy Sylvester matrix equations. The proposed methods are illustrated by numerical examples.
