Abstract

This paper is concerned with the design of networked controlsystems with random network delay in the forward and feedback channels and gives stability criteria of closed-loop networked predictive control systems. The principle of the predictor is adopted to overcome the effects of network delay. The necessary and sufficient conditions on the stability of the closed-loop networked control system are derived, which provide useful analytical stability criteria. It is shown that closed-loop networked predictivecontrol system with bounded random network delay is stable ifthe corresponding switched system is stable.
