Unlike a traditional topology of a control system with feedback connected plant and controller systems, this paper discusses a new topology that uses an intermediate network system between the plant and controller systems. More specifically, this paper presents modeling frameworks as well as computational procedures for the design of the closed-loop control system when the nodes of the plant, controller, and network systems fail to operate and the communication links fail to transfer information between communicating nodes. It also discusses conditions required for the synthesis of the controller and network systems, and characterizes the maximum number of unavailable nodes and the maximum probability of unavailable communication links. The aim of the presented results is to provide a more practical approach to the design of the new topology. Also, a four-tank process system is used to demonstrate details of the presented modeling frameworks and computational procedures.
