| 摘 要： | 网络控制系统(NCS)中的被控对象是包含工业控制对象和通讯网络的广义被控对象，其模型是时变不确定的，十分复杂。在考虑了单包传输、多包传输、数据包丢失、延时、随机干扰等情况下，用一种统一的形式，建立网络控制系统的模型。对广义被控对象进行分析和建模有利于网络控制系统控制器的分析和设计。在实际工程应用中在分析了NCS网络特性基础上。皆可按该方法对广义被控对象建模，然后再进行控制器设计。

| Abstract: | The controlled plant of the networked control system is the augmented plant including the industrial process and communication network. The model of the augmented plant is time-various and uncertain, so it is very complicated. An uniform model is developed to describe the augmented plant considering single-packet transmission, multiple-packet transmission, packets dropout, network-induced delay and noise etc. To analyze and to model the augmented plant is the basis of analyzing and designing the controller. In practice, all augmented plants can be modeled with this method based on the analysis of the networked control system, then the controllers can be designed. |
