Stability analysis for a networked control system with two additive input delays is considered.By spitting the whole delay interval into three subintervals, a new Lyapunov Krasovskii functional is constructed, which can make full use of the information of all the delays.Then, based on the constructed Lyapunov Krasovskii functional and using Wirtinger based inequality, sufficient conditions are derived to ensure the global asymptotic stability of the networked control system.Finally, a numerical example is provided to show the effectiveness of the criterion.In comparison with the known results, the obtained stability criterion is less conservative.
