摘　　要：针对多采样和空采样下的信息处理问题,提出了2种采样信息处理器方案.方案1在空采样时使用上一个采样周期的信息,多采样时采用最新数据报.方案2将多采样时收到的数据报滞后到空采样的时间段上.通过仿真和实验对这2个方案进行了对比.研究结果使在因特网上的远程位置控制成为可能,并指明了进一步研究的方向.To solve the problem of information processing in the over-sampled and empty-sampled cases, two schemes of sampled-information processors are proposed. In the first scheme information at a former sampling period is adopted in the empty-sampled case, and the last datagram is adopted in the over-sampled case. In the second scheme datagrams in the over-sampled case are postponed to the period in the empty-sampled case. Comparison is made between those two schemes. Result of study shows the feasibility of controlling position servo through Internet, and points out the directions of further study.
