Abstract
This paper deals with the class of uncertain systems with
multiple time delays. The stability
and stabilizability of this class of systems are considered.
Their robustness are also studied when the norm-bounded
uncertainties are considered. Linear matrix inequality
(LMIs) delay-dependent sufficient conditions for both
stability and stabilizability and their robustness are
established to check if a system of this class is stable and/or
is stabilizable. Some numerical examples are provided to show the
usefulness of
the proposed results.
