%X The non-fragile H-infinity filtering for a class of linear systems described by Delta operator is investigated. The designed filter is assumed to be with multiplicative filter gain variations. The sufficient condition is developed for the existence of the non-fragile filter design in terms of linear matrix inequality(LMI), and the obtained non-fragile H-infinity filter guarantees the filter error system of asymptotic stability and prescribed disturbance attenuation performance for a restricted variation of filter gain. The numerical example illustrates the feasibility and advantage of the proposed designs.
