This paper studies the problem of network induced delay and packet dropout compensation for continuous time networked control systems (NCSs). By proposing the one step prediction-based packet dropout compensation method, new model for NCSs with packet dropout and network-induced long delay is presented. Then, a packet dropout compensation threshold time based Lyapunov functional is proposed, and H-infinity controller design method is presented. Even for NCSs without packet dropout compensation, the obtained result is still less conservative than the existing ones. This paper proves also that some existing results can be improved by using the convex analysis method. Numerical examples are given to illustrate the merits and effectiveness of the proposed methods.
