具有数据包丢失的NCS反馈调度研究
Study on Feedback Scheduling for NCS with Packet Losses
【摘要】 网络化控制系统数据包丢失会导致控制系统性能下降与网络资源利用率降低。该文分析了网络化控制系统的数据包丢失问题,基于网络利用率,采用反馈调度方法,动态调整网络化控制系统控制任务周期,在线分配网络资源,实现调度与控制的集成,提高了网络资源的利用率与控制系统性能,仿真结果表明该方法的有效性。
【Abstract】 The data packet dropout degrades the performance and network utilization of networked control system. Based on network utilization, a feedback scheduler is used to adjust the sampling periods for tasks of NCS and network resources. The integrated control-scheduling is realized and the total control performance is optimized. The emulation result shows its effective.
