Abstract
In this paper, we provide the annular bound, i.e., lower and upper circular bound, for the roots of characteristic equations of uncertain discrete systems. Such an annular bound can be easily obtained by estimating the largest nonnegative zero of the specific polynomial. Two examples are also provided to show that the proposed annular bound is less conservative than the existing one reported recently.
