Abstract
The paper deals with the problem of determination of stability margin of uncertain linear discrete-time systems with uncertainty described by fuzzy numbers. Nonsymmetric triangular membership functions describing the uncertainty of coefficients of characteristic polynomial are considered. The presented solution is based on transformation of the original problem to Hurwitz stability test and generalization of Tsypkin-Polyak plot.
