In this paper, the scheduling problem of the network with limited bandwidth is considered. In order to improve the network quality of service and the quality of control simultaneously, an intelligent feedback scheduling method is proposed. The scheduler reschedules the priority, the sampling period, and the output threshold concurrently according to the control authority of each node, which is calculated by the fuzzy logic. Furthermore, the scheduler assigns the network resource to the node whose performance is worse, improves the network resource utilization, and reduces the network use. Simulation results are provided to show that the proposed method can improve system performance obviously and reassign the network resource effectively.
