| Abstract: | For an uncertain system described by convex combination of interval polynomials, its Hurwitz_stability can be guaranteed by certain subset composed of vertices and edges. Furthermore, the testing set does not increase when the order of given system increases. |
| Keywords: | interval polynomials convex combination of polynomials Hurwitz_stability value set |
