Sampled-Information Processor in the Telecontrol Systems

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.
