The Design of QoS Guarantee Strategy Framework for Networked Control System

For networked control systems such as packet loss and delay of the basic problems, this article launches the research from the perspective of network scheduling optimization, build the QoS semantic model and service model for networked control, puts forward the multi-level QoS guarantee strategy deployment algorithm and QoS, QoS access algorithm components; On a class of networked control middleware prototype system of network resources to meet of components and component deployment simulation experiment, the results show that by properly adjusting the bandwidth of the task node and priority, and controlling the efficient transmission of information, so as to shorten the network time delay, improve the network performance, increase the efficiency of the controller.
