| 摘 要： | 作为系统分析和设计的基础,对网络控制系统建立合适的模型,意义尤显重要。本文对广义被控对象进行了分析,考虑了延时、系统噪声和数据包丢失的情况下,用一种统一的形式,建立了多包传输网络控制系统的模型。在系统中,传感器采用时间驱动方式,控制器和执行器采用事件驱动方式。这些模型的建立有利于网络控制系统的分析和网络控制系统控制器的设计。

| Abstract: | The insertion of a communication network in the feedback control loop produces the time delays inevitably.The existence of transmission delay makes the analysis and design of a NCS more complex and difficult,especially the NCS with multi-packet transmission.Based on the reasons analyzing for multi-packet transmission in network,the object modeling of a network control system(NCS) with multi-packet transmission has been studied.The sensors are time-driven,the controllers and actuators are event-driven in the MIMO NCS.This paper presents the model of NCS with multi-packet transmission under considering system noise,packets dropout and network-induced delay etc.Finally some future research works in this field are highlighted. |
