摘要
网络控制系统由于将通讯网络引入了控制系统的闭环中,使得对其分析非常复杂。在分析网络多包传输原因的基础上,讨论了多包传输网络控制系统的建模问题。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。在考虑延时小于一个采样周期情况下,建立了多包传输闭环网络控制系统模型,并分析了闭环网络控制系统的稳定性。
The application of network control system is more and more widespreaded along with the rapid development of internet.The insertion of communication network to feedback control loop makes the analysis of network control system complicated.The plant modeling of network control system（NCS） with multi-packet transmission is discussed firstl The sensors are time-driven,the controllers and actuators are event-driven in the NCS.The model of NCS with multiple-packet transmission under considering network-induced delay less than one sampling including the stability of closed-loop system is presented and discussed.
