Abstract :
In this paper, we first establish a sufficient condition for the Schur stability, then use that result to establish a necessary and sufficient condition for the robust Schur stability of interval polynomial, from which an algorithm is developed to determine the Schur stability of interval polynomial. Finally, a numerical example is given to demonstrate the applicability of our algorithm.
