摘　　要：针对基于交换式以太网的网络化控制系统的数据传输和控制性能优化问题,提出了传感器根据给定值与实测值差额的绝对值对照静态调度表变采样周期的调度优化方法。使用True Time 2.0工具箱搭建了交换式以太网控制系统仿真平台进行仿真研究,并与定采样周期方法进行了对比,仿真结果验证了其可行性。此方法在实际的工程应用中具有一定的参考价值。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.
