Schur stability of polytopic systems through positivity analysis of matrix-valued polynomials


This paper is concerned with robust stability of uncertain discrete-time linear systems. The matrix defining the linear system (system matrix) is assumed to depend afflnely on a set of time-invariant unknown parameters lying on a known polytope. Robust stability is investigated by checking whether a certain integer power k of the uncertain system matrix has… (More)
