Modeling and management of networked control systems

A new method was formulated for modeling discrete networked control systems which have both time-varying delay and packet loss.Using the model,the stability and controller design needs of networked control systems were analyzed.Sufficient conditions to asymptotically stabilize the system were possible using the free-weighting matrices method and the Lyapunov-Krasovskii function.The introduction of free-weighting matrices reduced the conservatism of results obtained with the fixed-weighting matrices method.A controller to stabilize the system and an algorithm to provide maximum delay when the system was stable were presented.A simulation was run that illustrated the feasibility of the proposed approach.
