The delays can be observed and their probability distribution is assumed to be known. Under a few additional hypotheses the authors derive optimal controls for a corresponding LQG problem. They provide an example which shows how their solution performs in comparison with other (suboptimal) controls proposed in the literature.<div class="reviewer"> Reviewer:&nbsp;<a href="/authors/?q=rv%3A5633">M.Scheutzow (Berlin)</a></div> <div class="clearfix"></div></div> <div class="clear"></div> <br> <div class="citations"><div class="clear"><a href="/?q=rf%3A1192906">Cited in <strong>174</strong> Documents</a></div></div> <div class="classification"> <h3>MSC:</h3> <table><tr> <td> <a class="mono" href="/classification/?q=cc%3A93E20" title="MSC2020">93E20</a> </td> <td class="space"> Optimal stochastic control </td> </tr><tr> <td> <a class="mono" href="/classification/?q=cc%3A93C83" title="MSC2020">93C83</a> </td> <td class="space"> Control/observation systems involving computers (process control, etc.) </td> </tr><tr> <td> <a class="mono" href="/classification/?q=cc%3A93C57" title="MSC2020">93C57</a> </td> <td class="space"> Sampled-data control/observation systems </td> </tr></table> </div><div class="keywords"> <h3>Keywords:</h3><a href="/?q=ut%3Arandom+delays">random delays</a>; <a href="/?q=ut%3Adelay+compensation">delay compensation</a>; <a href="/?q=ut%3Adistributed+computer+control+systems">distributed computer control systems</a>; <a href="/?q=ut%3Areal-time+systems">real-time systems</a>; <a href="/?q=ut%3Astochastic+control">stochastic control</a>; <a href="/?q=ut%3Astochastic+parameters">stochastic parameters</a>; <a href="/?q=ut%3Atiming+jitter">timing jitter</a></div> <!-- Modal used to show zbmath metadata in different output formats--> <div class="modal fade" id="metadataModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel"> <div class="modal-dialog" role="document"> <div class="modal-content"> <div class="modal-header"> <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button> <h4 class="modal-title" id="myModalLabel">Cite</h4> </div> <div class="modal-body"> <div class="form-group"> <label for="select-output" class="control-label">Format</label> <select id="select-output" class="form-control" aria-label="Select Metadata format"></select> </div> <div class="form-group"> <label for="metadataText" class="control-label">Result</label> <textarea class="form-control" id="metadataText" rows="10" style="min-width: 100%;max-width: 100%"></textarea> </div> <div id="metadata-alert" class="alert alert-danger" role="alert" style="display: none;"> <!-- alert for connection errors etc --> </div> </div> <div class="modal-footer"> <button type="button" class="btn btn-primary" onclick="copyMetadata()">Copy to clipboard</button> <button type="button" class="btn btn-default" data-dismiss="modal">Close</button> </div> </div> </div> </div> <div class="functions clearfix"> <div class="function"> <!-- Button trigger metadata modal --> <a type="button" class="btn btn-default btn-xs pdf" data-toggle="modal" data-target="#metadataModal" data-itemtype="Zbl" data-itemname="Zbl 0908.93073" data-ciurl="/ci/01192906" data-biburl="/bibtex/01192906.bib" data-amsurl="/amsrefs/01192906.bib" data-xmlurl="/xml/01192906.xml" > Cite </a> <a class="btn btn-default btn-xs pdf" data-container="body" type="button" href="/pdf/01192906.pdf" title="Zbl 0908.93073 as PDF">Review PDF</a> </div> <div class="fulltexts"> <span class="fulltext">Full Text:</span> <a class="btn btn-default btn-xs" type="button" href="https://doi.org/10.1016/S0005-1098(97)00170-2" aria-label="DOI for “Stochastic analysis and control of real-time systems with random time delays”" title="10.1016/S0005-1098(97)00170-2">DOI</a> </div> <div class="sfx" style="float: right;"> </div> </div> <div class="references"> <h3>References:</h3> <table><tr> <td>[1]</td> <td class="space">Anderson, B.
