This paper concentrates on analyzing the stability problems of aperiodic sampled-data systems with time delay.Based on Lyapunov theory, a new time-square-dependent two-side looped-functional (TTLF) is proposed, which can take full advantage of the Waterproof Overtrousers second order terms with respect to time.And by using the intrinsic relationshi
