Title: Robust stability of discrete interval systems. 9 p.
Language: English
Keywords: Robust stability; discrete systems; interval polynomials.
ABSTRACT. A linear-fractional mapping with a free parameter is introduced
on the complex plane which transforms the unit circle into itself. This mapping
doesn' alter the stability properties of a discrete system. The free parameter
variation in a fixed region allows to relax sufficient robust stability
conditions.
