Abstract
In this paper we study the robust stability independent of delay of some class of uncertain quasipolynomials, whose coefficients may vary in a certain prescribed range. Our main contributions include frequency-sweeping conditions for interval, diamond and spherical quasipolynomial families. The corresponding results provide necessary and sufficient conditions, and are easy to check, requiring only the computation of two simple frequency-dependent functions.
