摘要
随着网络技术日趋成熟,以太网络在控制系统中的应用也成为研究热点之一。稳定性是NCS能够正常工作的首要条件,然而时延的存在给网络控制系统带来了很大的不确定性。在对时延进行分析后,针对时延的主要部分解决问题,并提出了指令推测技术,为EthernetNCS响应时间保障机制提供理论基础。
With the development and maturity of network technology, Ethernet is becoming one of hotspots in application of control system. Stability is the first condition which NCS can work in gear. However, existence of time-delay brings great uncertainty to NCS. After analyzing time-delay and account for some questions according to main of time-delay, instruction speculation technology is brought forward in this paper, which offers theory basis for NCS response time guarantee mechanism.
