Observer-based control for networked control systems with network induced delay and packet dropout

The problem of the delay-dependent observer-based control for networked control systems is described under the concerns of the synthesis effect of sampled-data, network induced delay, packet dropout and disordering. By using the lyapunov-krasovskii functionals, delay dependent criteria are given to guarantee the stability of the delay dependent observer-based control systems. In terms of linear matrix inequality techniques, the controller gain, observer gain and maximum allowable delay bound of networked control systems can be given from the linear matrix inequality feasible solutions. Finally, a numerical example is given to show the effectiveness of the proposed design method.
