This paper deals with the stochastic stability of networked control systems with the presence of networkinduced delay and transmitted data dropout.Based on the Lyapunov approach.safficient conditions for the mean-square stability of the networked control system are derived subiect that the sequence of transmission interval is driven by an identicaily independently distributed sequence and by a finite state Markov chain.respectively.Stabilization controllers are constructed in tcrims of linear matrix inequalities correspondingly.An example is provided to illustrate our results.
