| Abstract: |
| In this paper, we considered the rank range of the solutions of a class of matrix equations. By applying the singular value decomposition of matrix and the properties of Frobenius matrix norm, we obtained the extremal rank and the solution expression of under rank constrained. Some special cases of theses problems are considered, and some results are obtained. |
| Key words: optimal control extremal rank SVD decomposition Frobenius matrix norm |
