Notice of RetractionStability of networked control systems with random time delay

The insertion of the communication network in feedback control loop makes the analysis and design of networked control systems (NCS) more complex, and induces some issues that degrade the control system's performance and even cause instability. This paper discusses the analysis of a networked control system whose sensors and actuators exchange information with a remote controller over a shared network. The design of the controller is done in discrete domain without delay. The contribution of this work is the use of mean square and almost sure stability for NCS with stochastic random delay of the augmented system in closed loop.
