This paper discusses robust H ∞ disturbance attenuation for an uncertain system with time‐varying delay. An appropriate Lyapunov functional, which takes into account the range of time‐delay and its derivative, is introduced to investigate robust H ∞ disturbance attenuation. Less conservative results are obtained by such a Lyapunov functional with model transformation method and free weighting matrix method. Numerical examples are given to show the effectiveness of the proposed method. © 2010 Wiley Periodicals, Inc.
