This paper proposes a system topology for potential use as a Wireless Networked Control System (WNCS). The topology has a plant to be regulated, a dedicated controller that makes control decisions, and an intermediate network of nodes. The network assists the controller in stabilizing the closed-loop system and provides the means for connecting the sensors and actuators of the plant and the inputs and outputs of the controller. Further, the paper presents a framework for modelling the closed-loop system such that controller and network systems can be designed. The paper also provides an LMI-based algorithm for computing optimal controller and network systems that achieve a stable closed-loop system while meeting performance measures. The deigned systems have a fixed structure and hence the associated design complexity is reduced. Finally, the paper also illustrates with examples the effectiveness of the proposed design and computational procedures.
