| Abstract: | The problem of robust H_infty control is investigated for a class of linearsystems with uncertainty and time varying delay. A new type of Lyapunov-Krasovskii functional based on fractioning the average delay approach is presented to analyze the stability for this kind of systems. The delay-dependent conditions are proposed in terms of linear matrix inequality(LMI). Then the robust controller is presented through analyzing the stability of the closed-loop system. A numerical example is also given to illustrate the effectiveness of the proposed method. |
