| 给出矩阵方程 AX-EXY=BY的一个完全解析的、具有显式表达式和完全自由度的参数解 (X,Y) .这里假设矩阵束 (E,A,B) 为R-能控的, F为任意的方阵.相比于现有结论,求解算法不要求矩阵A和F具有特殊的形式,且对它们的特征值没有任何的限制.此外,本文给出的通解还具有结构简洁的特点.作为一个应用,给出了广义系统正常Luenberger函数观测器的一种参数化的设计方法.算例证明了方法的有效性. |
| 英文摘要 |
| The problem of solving the matrix equationAX-EXY = BY is studied in this paper. Firstly,a complete general parametric expression for (X,Y) satisfying this equation is obtained. Here matrix triple (E,A,B) is R-controllable and F is an arbitrary matrix. Compared with existing results, the algorithm does not need the matrices F and A to be in any canonical forms and the knowledge of their eigenvalues. Furthermore,this type of solution has a very neat form. As a demonstration, the Luenberger function observer design of descriptor linear system is considered and a parametric design procedure is established.Finally, a numerical example shows the effectiveness of the proposed approach.. |
