through the experiment, the delay characteristic is got . ( 4 ) to reduce the communication amount of ncs, the plant information is used in the controller node . the simulation shows that the sampling period guaranteed the system is stable is greatly enlarged, which shows that the proposed method helps to reducing the communication burden in ncs essentially (4)為了減少網絡控制系統中的通信量,考慮在控制器上利用對象的信息,通過仿真實例說明可使系統穩定的采樣周期大大增加,表明這種方法從本質上有助于解決網絡控制系統通信受限的問題。
