摘要：
This paper focuses on H (a) filter design for systems with time-varying delay. A delay-dependent H (a) performance analysis result is first established for error systems without ignoring any terms in the derivative of the Lyapunov functional by considering the relationship between the time-varying delay and its upper bound. Based on the derived H (a) performance analysis result, the H (a) filter is designed in terms of linear matrix inequalities (LMIs). The resulting criteria are extended to systems with polytopic-type uncertainties. Numerical examples are given to demonstrate the merits of the proposed method.
