In this paper, the passivity analysis of uncertain discrete switched systems with interval time-varying delay and linear fractional perturbations is achieved via switching signal design. Some LMI criteria are provided to design the switching signal to guarantee the passivity of discrete switched time-delay system. Some nonnegative inequalities are introduced to improve the conservativeness of the proposed results. Finally, a numerical example is illustrated to show the main proposed results.
