Contrapose data transmission and control performance majorization problem of the network control system based on switched Ethernet

propose a schedule optimization which use variable sampling period according to absolute value of the difference between set and measured values compared with static scheduling table. A switched Ethernet control system simulation platform is built by using Ture Time 2. 0 toolbox to perform simulation research and make a comparison with fixed sampling period method. Simulation results show feasibility of this method. This method has a certain reference value in practical engineering applications.
