摘要
由于在控制回路中引入了网络,给控制系统带来新的问题,其中最主要的问题之一是网络的时延问题,网络延时会降低控制系统的性能甚至引起系统不稳定.因此,许多研究者致力于研究开发新的控制方法以处理由于网络的引入而引起的时延问题.在此,把近年来国内外的研究方法及现状给予归纳总结,并就网络控制结构和网络时延特性及其影响给予介绍,最后提出其发展趋势.
Due to the use of network in a control loop, it could cause some new problems. One of the major problems in this so-called networked control system is the network-induced delay effect in the control loop. Network delays degrade the NCS control performance and destabilize the system. Many researchers have been on developing control methodologies to handle the network delay effect in NCS. It presents recent NCS control methodologies in this survey paper. The overview on NCS structures and description of network delays including characteristics and effects are also covered.
