| 摘 要： | 基于TCP/IP网络的远程控制系统有广阔的应用前景。控制系统中TCP/IP网络传送实时采样信息时发生的时延和时延的不确定性是影响该系统实用化的关键。通过在网络环境下进行的传输实时采样信息试验表明,如果时延小于控制系统的采样周期,那么它的影响可以忽略不计;如果大于采样周期,不确定性时延会使控制系统发生空采样、多采样及实时采样信息失真,这些现象对整个远程控制系统的影响以及相应的控制策略是今后研究的重点。

| Abstract: | TCP/IP network-based far control system have a profound application fields,In this system,the time delay and its uncertainty during the real_time sampling information transportation via TCP/IP net.is the key obstacle of its applications.This paper measures the delay during the transportation using TCP protocol in differrent network environ-ment ?The results indicates that the effect causing by delay can be ignored if they are less than one sampling period;in other status,the uncertainty cause multi-sampling,null-sampling and distortion of real_time sampling information,the main research will focus on the effects and solution of bad behavier causing by transportation delay and its uncertainty. |
