摘要： 为了消除网络控制系统中数据传输时延给控制品质带来的不良影响，从融合通信技术和控制技术的角度出发，提出一种新的控制方案：通过运用在线信息排队的方法，将实际的时间不确定延迟系统变成时间确定性的网络闭环系统；在此基础上，根据得到的确定性时延来确定PSD-Smith 预测控制器中的控制参数。此控制方案克服了对网络时延离线假设的盲目性，而且在具体实施中不需要网络同步时钟技术的支持，因此具有一定程度的实用性。通过对一阶、二阶纯滞后系统的仿真实验，其结果表明了此控制方案的有效性。

Abstract: To eliminate the bad influence on system control properties resulted from signal transition time-delay, a novel control strategy is proposed based on communication and control technology: Firstly, changing a variable time-delay system to a constant time-delay closed-loop system; Secondly, fixing the PSD controller’s parameters according to the constant time-delay system model. This control structure is practical worthing to be recommended because unreasoning assumption on network transition time-delay is overcome and it does not need the synchronization clock. Finally, this control strategy’s efficiency is proved by the simulation results of first-order and second-order plants
