Abstract In this paper, we consider the stability of time-delayed linear systems with a time-varying delay. Based on the new form of Lyapunov-Krasovskii functional(LKF), and by applying the second order Bessel-Legendre inequality and the improved reciprocally convex inequality, a stability result in the form of LMI is derived. Finally, the usefulness of the proposed result is shown by well-known two numerical examples.
