Network Control System Scheduling Algorithm Research And Simulation

Networked control systems are integration of controlling science, computing science and networking technology. The competition of network resource and network delay bring traditional control theories and methods new meanings and research directions, one important proportion of which is network scheduling. Based on existent results on control network performance and scheduling in protocol layer, the paper analyzes the scheduling algorithm of networked control systems in application layer, and structures multi-task networked control systems for scheduling simulation in virtual platform. Via the simulation, it is discussed how RM algorithm and EDF algorithm influence the performance of networked control systems, and presented the significance of EDF scheduling algorithm in networked control systems. Besides, the paper studies feedback-control real-time scheduling algorithms and their application in networked control systems.
