摘要
本文论述了网络控制系统的产生、特点、复杂性和发展优势,分析总结了在网络控制系统数据包丢失方面的主要研究成果和进展.根据灰色模型的预测性,提出了基于灰色控制理论对网络控制系统数据传输中包丢失补偿策略,并应用此补偿策略对网络控制倒立摆系统进行了仿真实验研究,仿真结果显示丢包补偿后的系统输出几乎与未丢包时一致,从而证实了所提研究策略的正确性与有效性.
This paper presents the history, and characteristic of the networked control systems （NCSs）, as well as the complexities and advantages of NCSs, summarizing the research results on NCSs packet dropout. Based on the prediction of Grey Model, a method to compensate for packet dropout is introduced, which is used in an inverted pendulum system controlled through network. The simulation shows that the output of packet dropout but compensated is nearly the same was no packet dropout, which verifies the correctness and effectiveness.
