Abstract :
This paper presents a new analytical method for checking the Schur stability of interval polynomial matrices. In particular, we suggest using Markov matrices of the nominal polynomial matrix to assess its stability. The proposed technique is algebraically simple and has a relatively small computational cost, yet the result is less conservative than an existing analytical solution. The validity of the suggested method is illustrated through examples
