Abstract :
This paper addresses the problem of testing whether a bivariate polynomial does not vanish in the product of the closed exterior of the unit-circle times the right half-plane. This requirement presents stability conditions for certain mixed continuous-discrete systems. An algebraic method to solve the problem in polynomial order of complexity is developed from Jury´s modified stability test (IEEE Trans. Circuits Syst., vol. 35, pp. 116-119, 1988).
