The two different processes are respectively: reverse process with time delay, tracking servo of DVD system.

这两类过程是：时滞反向响应过程和DVD循轨伺服系统。

The delay estimation and compensation are key problems in real-time substructure testing because the delay of servo-hydraulic loading system may induce failure due to experimental instability.

在实时子结构试验中，液压伺服加载系统的时滞可能导致试验因丧失稳定而失败，因而时滞估计和补偿是该类试验的关键问题之一。

With these parameters, a real-time track occurring rule is presented to match the bandwidth of the robot servo system and eliminate the influence of the delay involved in vision system.

有了上述参数，就可以设计与伺服系统带宽匹配、消除图像处理延时影响的目标轨迹生成器。
