Owing to the introduction works to control systems, network-induced delays and dropout packet phenomenon are almost unavoidable, which often degrade control performance and a? ect system stability. In fact, the issue of the controller design and stability analysis worked systems munication delays and data dropout isa really hard task. Recently, academic c ommunity for the research worked control system control strategy has got a lot of achievements, many effective methods were proposed. In this paper, in view of predictive control strategy, the basic principles of dynamic matrix algorithm and the parameters on the control performance is described. Key words : network control system; time delay; predictive control; dynamic matrix algorithm 0 引言随着网络技术和控制技术的不断发展,网络控制系统得到了广泛的应用,使得控制系统更加便捷。网络控制系统
