| 摘 要： | 针对单控制器多任务的交换式以太网控制系统数据传输和控制性能优化问题,提出了传感器主动退避冲突采样时间点的调度优化方法。使用True Time2.0工具箱搭建了单控制器多任务的交换式以太网控制系统仿真平台进行仿真研究,并与未采用此方法的传统系统进行了对比。仿真结果验证了其可行性。

| Abstract: | Aiming at both data transmission and optimizing control performance of single controller and multi-task switched ethernet control system,the scheduling optimization method for the sensor which actively retreating from the conflict sampling time and points was proposed.Making use of TrueTime2.0 toolbox to build a simulation platform for single controller and multi-task switched ethernet control system was implemented and then having it compared with traditional control system.The simulation results verify the feasibility of this method. |
