Abstract :
This paper provides stability conditions of an uncertain networked control system with both forward control signal loss and feedback output signal loss. It is assumed that both the forward control signal and the output measurement signal are intermittent independently, and the remote plant has a model uncertainty. Also, in this paper, an observer-based controller is used in the remote place because the full states are not accessible. Thus, the main research goal is to analyze the overall stability of this uncertain intermittent networked system. In the second part of this paper, we consider delay effects of both forward signal and feedback signal during the network transfer
