Networked control systems are one type of distributed real-time control systems where sensors, actuator and controllers are interconnected by communication networks. In networked control systems, the insertion of the communication network makes the analysis and design of a networked control system more complex. In the past, control system design and CPU scheduling or network scheduling design have normally been separated. But from the point of both the communication protocols and the interacting controlled system, they should not be treated as separate. Thus, a co-design approach is proposed. Firstly, transmission model for the networked control systems is defined when a set of networked control systems is connected to the network, the Rate Monotonic (RM) scheduling algorithm and the Earliest Deadline First (EDF) scheduling algorithm are introduced. Then, applying EDF scheduling algorithm with the Integral of the Absolute Error (IAE) to schedule a set of real-time networked control systems. Finally, a simulation example is given to implement EDF-IAE performance protocol. The simulation results show that EDF-IAE performance protocol is feasible.
