Robust Hurwitz and Schur Stability Test for Polytopes of Matrices
Xi Du · Journal of the China Railway Society · 1999
The necessary and sufficient conditions for the robust Hurwitz and Schur stability of interval matrices have been established by relying on a two dimensional (2 D) face test.We show that the stability of exposed 2 D faces of a polytope of matrices guarantees the stability of the polytope.An examples is given to demonstrate the applicability of our robust stability test of polytopes of matrices.
