【摘要】 综述了网络控制系统的出现背景、概念和特性,阐明了网络的应用给传统控制系统带来的益处及广阔的应用前景,分析了网络传输数据给网络控制系统带来的问题,并阐述了网络控制系统中不同于一般网络系统的通信问题,详细分析了近年来迅速发展的现场总线和以太网在分布式网络控制系统中的发展趋势。最后概述了网络控制系统当前的研究现状。指出将网络通信调度和系统控制结合起来,将基于假设的理论研究同基于实际对象的实验平台相结合,是未来的发展趋势。更多还原

【Abstract】 The developing background of networked control systems is summarized.The benefit and expansive application foreground applying networks brings to traditional control systems are illuminated.The problems existing in networked control systems when data is transmitted by network are put forward.And networked control systems’ communication problems which differ from normal network systems are expatiated.The developing trend of Field-bus and Ethernet in distributed networked control systems is analyzed.At last,current study status of networked con- trol systems is summarized.Future study should combine network communications attemperring with systems control,and combine theory re- search based upon suppose with experiment based upon actual object.更多还原
