Abstract: This paper deals with the controller design of a networked control system with the presence of network-induced delay and transmitted data dropout.In view of data loss and network-induced delay,the networked control system is modelled as a stochastic switching discrete-time linear system with delay.By means of Lyapunov me-(thod),a novel delay-dependent condition is given,which enables the networked control system to be asymptotically stable in the mean-square sense.Based on this condition,the desired controller is constructed through solving a set of linear matrix inequalities.An example is presented to illustrate the effectiveness of the proposed method.
