For networked control systems with limited network bandwidth, the conflict will reduce control performance of the system. This paper puts forward a new dynamic scheduling. This method guarantees the quality of control (output is into its steady state value: −5 to 5 % range) as the goal, and set deadband in the controller. It bases on the two parameters: error and error change rate adaptive to adjust the network load. Lastly, do the simulation based on CSMA/CD network simulation. The results verify the proposed method can improve the utilization rate of the network bandwidth, to improve the quality of control performance, enhance the stability of the system.
