A new model is proposed to describe the filtering system with random sensor-filter delay which may be longer than one sampling period. The random delay is modeled as a Markov chain and the resulting filtering error system is a Markovian switched system with random state delay. By using a properly constructed Lyapunov function and the state transform technique, sufficient conditions for the existence of the $H_{\infty }$ filters are presented in terms of linear matrix inequalities. An optimization problem with LMIs constraints is formulated to design the $H_{\infty }$ filter which guarantees that the filtering error system is mean-square exponentially stable with a prescribed decay rate and ensures an optimal $H_{\infty }$ disturbance attenuation level. An illustrative example is given to demonstrate the effectiveness of the proposed results.</div> <div class="clear"></div> <br> <div class="citations"><div class="clear"><a href="/?q=rf%3A5539823">Cited in <strong>33</strong> Documents</a></div></div> <div class="classification"> <h3>MSC:</h3> <table><tr> <td> <a class="mono" href="/classification/?q=cc%3A93E11" title="MSC2020">93E11</a> </td> <td class="space"> Filtering in stochastic control theory </td> </tr><tr> <td> <a class="mono" href="/classification/?q=cc%3A93B36" title="MSC2020">93B36</a> </td> <td class="space"> $H^\infty$-control </td> </tr></table> </div><div class="keywords"> <h3>Keywords:</h3><a href="/?q=ut%3A%5C%28H_%7B%5Cinfty+%7D%5C%29+filtering">$H_{\infty }$ filtering</a>; <a href="/?q=ut%3Arandom+delay">random delay</a>; <a href="/?q=ut%3AMarkov+chain">Markov chain</a>; <a href="/?q=ut%3Amean-square+exponential+stability">mean-square exponential stability</a>; <a href="/?q=ut%3Alinear+matrix+inequalities+%28LMIs%29">linear matrix inequalities (LMIs)</a></div>  <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">×</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;">  </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">  <a type="button" class="btn btn-default btn-xs pdf" data-toggle="modal" data-target="#metadataModal" data-itemtype="Zbl" data-itemname="Zbl 1157.93529" data-ciurl="/ci/05539823" data-biburl="/bibtex/05539823.bib" data-amsurl="/amsrefs/05539823.bib" data-xmlurl="/xml/05539823.xml" > Cite </a> <a class="btn btn-default btn-xs pdf" data-container="body" type="button" href="/pdf/05539823.pdf" title="Zbl 1157.93529 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/j.sigpro.2008.10.005" aria-label="DOI for “$H_\infty $ filtering of network-based systems with random delay”" title="10.1016/j.sigpro.2008.10.005">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">Zhang, W.; Branicky, M.
