This note is concerned with the problem of a robust and non - fragile H∞ filter design for a class of polytopic uncertain discrete - time systems. The filter to be designed is assumed to be with multiplicative filter gain variations. Exploited to develop sufficient conditions for the robust and non - fragile filter design in terms of linear matrix inequality (LMI). A numerical example illustrate the feasibility and advantage of the proposed design methods.
