This paper presents the formulation, modelling and design of a fixed structure topology for potential application in wireless networked control systems. The topology consists of a standard plant system, an output feedback controller system, and intermediate transfer and receiving network systems. The paper defines the topology and addresses the modelling of the closed-loop control system. It presents a modelling framework to design the controller, the transfer network, and the receiving network systems. Also, the paper discusses a design procedure of using shared network systems for a closed-loop control system with multiple plant and controller systems. The design procedures utilize LMI-based algorithms and deliver an internally stable closed-loop control system whose inputs and outputs satisfy an l 2  – l ∞  performance criterion. The practicality of the design procedures is demonstrated using an illustrative example.
