摘要：

四元数线性系统在控制理论和工程中有广泛的应用。利用矩阵半张量积对四元数矩阵方程进行研究，提出四元数矩阵的一种实向量表示并研究其性质。结合实向量表示与矩阵半张量积，给出四元数矩阵方程$A^HXA=B$的极小范数Hermitian解的存在条件及通解表达式，并且给出相应算法。数值实验证明了实向量表示方法的可行性。

Abstract:

Quaternion linear systems have wide applications in both the control theory and engineering. Quaternion matrix equations are studied by means of semi-tensor product of matrices. A real vector representation of quaternion matrix is presented and its properties are studied. Combining the real vector representation and the semi-tensor product of matrices, the equivalent conditions for existence of Hermitian solution and the expressions of the minimal norm Hermitian solution of quaternion matrix equation $A^HXA=B$ are proposed, and the corresponding algorithm is given. The effectiveness of the real vector representation method is verified by numerical experiments.

Key words: quaternion matrix equation, Hermitian matrix, semi-tensor product of matrices, real column (row) stacking form, swap matrix
