Abstract. In this paper, we study the problem of stability analysis for
discrete-time linear
system with interval time-varying delay and nonlinear perturbations.
By constructing a new Lyapunov-Krasovskii functional with triple
summation terms, mixed model transformation, Jensen-type summation
inequality and utilization of zero equation, new
delay-range-dependent asymptotic stability criteria are obtained
and formulated in terms of linear matrix inequalities (LMIs).
Moreover, we obtain new delay-range-dependent asymptotic stability
criteria of discrete-time linear
system with interval time-varying delay.
Numerical examples are given to demonstrate the
effectiveness and less conservativeness of the proposed methods.
