In this paper, a fundamental stabilization problem is investigated for a class of sampled-data systems under noisy sampling interval. The stochastic sampled-data control system under consideration is first converted into a discrete-time system whose system matrix is represented as an equivalent yet tractable form via the matrix exponential computation. Then, by introducing a Vandermonde matrix, the mathematical expectation of the quadratic form of the system matrix is computed. By recurring to the Kronecker product operation, a sampled-data stabilization controller is designed such that the closed-loop system is stochastically stable in the presence of noisy sampling interval. Subsequently, a special case is considered where the sampling interval obeys the continuous uniform distribution and the corresponding stabilization controller is designed. Finally, a numerical simulation example is provided to demonstrate the effectiveness of the proposed design approach.</div> <div class="clear"></div> <br> <div class="citations"><div class="clear"><a href="/?q=rf%3A6524060">Cited in <strong>27</strong> Documents</a></div></div> <div class="classification"> <h3>MSC:</h3> <table><tr> <td> <a class="mono" href="/classification/?q=cc%3A93E15" title="MSC2020">93E15</a> </td> <td class="space"> Stochastic stability in control theory </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><tr> <td> <a class="mono" href="/classification/?q=cc%3A93C55" title="MSC2020">93C55</a> </td> <td class="space"> Discrete-time control/observation systems </td> </tr><tr> <td> <a class="mono" href="/classification/?q=cc%3A93B50" title="MSC2020">93B50</a> </td> <td class="space"> Synthesis problems </td> </tr></table> </div><div class="keywords"> <h3>Keywords:</h3><a href="/?q=ut%3Amatrix+exponential">matrix exponential</a>; <a href="/?q=ut%3Anoisy+sampling+interval">noisy sampling interval</a>; <a href="/?q=ut%3Asampled-data+control+systems">sampled-data control systems</a>; <a href="/?q=ut%3Astochastic+control">stochastic control</a>; <a href="/?q=ut%3Asynthesis+of+stochastic+systems">synthesis of stochastic systems</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 1329.93149" data-ciurl="/ci/06524060" data-biburl="/bibtex/06524060.bib" data-amsurl="/amsrefs/06524060.bib" data-xmlurl="/xml/06524060.xml" > Cite </a> <a class="btn btn-default btn-xs pdf" data-container="body" type="button" href="/pdf/06524060.pdf" title="Zbl 1329.93149 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.automatica.2015.10.005" aria-label="DOI for “Stabilization for sampled-data systems under noisy sampling interval”" title="10.1016/j.automatica.2015.10.005">DOI</a> <a class="btn btn-default btn-xs" type="button" href="http://bura.brunel.ac.uk/handle/2438/11791" title="Full Text Link">Link</a> </div> <div class="sfx" style="float: right;"> </div> </div> <div class="references"> <h3>References:</h3> <table><tr> <td>[1]</td> <td class="space">Alexandre, S., A novel stability analysis of linear systems under asynchronous samplings, Automatica, 48, 1, 177-182 (2012) &middot; <a href="/1244.93095" class="nowrap">Zbl 1244.93095</a></td> </tr><tr> <td>[3]</td> <td class="space">Ding, D.; Wang, Z.; Lam, J.; Shen, B., Finite-horizon \(H_\infty\) control for discrete time-varying systems with randomly occurring nonlinearities and fading measurements, IEEE Transactions on Automatic Control, 60, 9, 2488-2493 (2015) &middot; <a href="/1360.93646" class="nowrap">Zbl 1360.93646</a></td> </tr><tr> <td>[4]</td> <td class="space">Ding, D.; Wang, Z.; Shen, B.; Dong, H., Envelope-constrained \(H_\infty\) filtering with fading measurements and randomly occurring nonlinearities: the finite horizon case, Automatica, 55, 37-45 (2015) &middot; <a href="/1378.93125" class="nowrap">Zbl 1378.93125</a></td> </tr><tr> <td>[5]</td> <td class="space">Dong, H.; Wang, Z.; Gao, H., Distributed \(H_\infty\) filtering for a class of Markovian jump nonlinear time-delay systems over lossy sensor networks, IEEE Transactions on Industrial Electronics, 60, 10, 4665-4672 (2013)</td> </tr><tr> <td>[6]</td> <td class="space">Fridman, E.; Seuret, A.; Richard, J.
