The analysis of permissible quality indices of the system with affine uncertainty of characteristic polynomial coefficients

The goal of this article is to analyze the assurance of permissible quality indices in an interval system through the construction of the edge route and the use of D-partition method. There were obtained conditions for construction of D-partition domains on one and two edges of one face. On the basis of these conditions the technique for assurance of the permissible degree of robust stability and oscillation was developed. The article presents a numerical illustration.
