Abstract

Networked control systems are one type of distributed real-time control systems where sensors, actuator and controllers are interconnected by communication networks. The insertion of the communication network makes the analysis and design of a networked control system complex. So the performance of the control loops not only depends on the design of the control algorithms, but also on the scheduling of the shared network resource. A co-design method based on the integrated Earliest Deadline First (EDF) scheduling algorithm and the Integral of the Absolute Error (IAE) is proposed in order that the communication medium is more efficiently used and control performance is improved. The presented method can adjust the sampling period, handle three types of message and guarantees real-time transmission of periodic and aperiodic message, and non-real time message. The simulation results show that the proposed co-design method is available and improve the system resources efficiency.
