| Abstract: | The robust stability of uncertain neutral system with interval time-varying delay is studied. The new stability criteria are obtained by constructing appropriate Lyapunov-Krasovskii functional and combining integral inequality handling techniques, free weight matrix and convex combination. Numerical simulations are given to show the effectiveness of the proposed approach and the results of this paper are compared with the existing cited results. It shows that the method proposed in this paper improves the known results and shows less conservatism. |
