Abstract: For time-varying delay linear systems with intervals, a new Lyapunov-Krasovskii method was presented to analyze the stability of linear systems with interval time-varying delay, and design a non-fragile robust H∞ controller. The non-fragile robust H∞ controller guaranteed the time-delay systems were asymptotically stable and satisfied a prescribed H∞ performance level. The non-fragile robust H∞ controller of linear systems with interval time-varying delay can be solved by linear matrix inequality (LMI). The effectiveness of the proposed design method was verified by simulation examples.
