Abstract :
In this paper, the expansion of det(A+B+C) is given. The robustness problem for discrete-time state-space systems with uncertain parameters is investigated by applying the Schur stability theory of interval polynomials. A stability robustness criterion for the uncertain systems is derived. Illustrative examples are presented
