The estimated actuator failure from a fault observer is utilized to construct an improved performance index function that reflects the failure, regulation and control simultaneously. By employing a proper performance index function, the FTC problem can be transformed into an optimal control problem. By using policy iteration, the Hamilton-Jacobi-Bellman equation can be solved by constructing a critic neural network. Then, the approximated optimal controller can be derived directly. The closed-loop system is guaranteed to be uniformly ultimately bounded via the Lyapunov stability theorem. The effectiveness of the developed FTC scheme is demonstrated by two simulation examples. The significant contribution of the proposed strategy lies in that the well-known ADP method is extended to solving the FTC problem.</div> <div class="clear"></div> <br> <div class="citations"><div class="clear"><a href="/?q=rf%3A7164152">Cited in <strong>21</strong> Documents</a></div></div> <div class="classification"> <h3>MSC:</h3> <table><tr> <td> <a class="mono" href="/classification/?q=cc%3A93C40" title="MSC2020">93C40</a> </td> <td class="space"> Adaptive control/observation systems </td> </tr><tr> <td> <a class="mono" href="/classification/?q=cc%3A93B53" title="MSC2020">93B53</a> </td> <td class="space"> Observers </td> </tr><tr> <td> <a class="mono" href="/classification/?q=cc%3A90C39" title="MSC2020">90C39</a> </td> <td class="space"> Dynamic programming </td> </tr><tr> <td> <a class="mono" href="/classification/?q=cc%3A93B35" title="MSC2020">93B35</a> </td> <td class="space"> Sensitivity (robustness) </td> </tr><tr> <td> <a class="mono" href="/classification/?q=cc%3A93B70" title="MSC2020">93B70</a> </td> <td class="space"> Networked control </td> </tr><tr> <td> <a class="mono" href="/classification/?q=cc%3A93C10" title="MSC2020">93C10</a> </td> <td class="space"> Nonlinear systems in control theory </td> </tr></table> </div><div class="keywords"> <h3>Keywords:</h3><a href="/?q=ut%3Aadaptive+dynamic+programming">adaptive dynamic programming</a>; <a href="/?q=ut%3Afault+tolerant+control">fault tolerant control</a>; <a href="/?q=ut%3Apolicy+iteration">policy iteration</a>; <a href="/?q=ut%3Anonlinear+systems">nonlinear systems</a>; <a href="/?q=ut%3Afault+observer">fault observer</a>; <a href="/?q=ut%3Aneural+network">neural network</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">×</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 1432.93185" data-ciurl="/ci/07164152" data-biburl="/bibtex/07164152.bib" data-amsurl="/amsrefs/07164152.bib" data-xmlurl="/xml/07164152.xml" > Cite </a> <a class="btn btn-default btn-xs pdf" data-container="body" type="button" href="/pdf/07164152.pdf" title="Zbl 1432.93185 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.ins.2016.12.016" aria-label="DOI for “Observer based adaptive dynamic programming for fault tolerant control of a class of nonlinear systems”" title="10.1016/j.ins.2016.12.016">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">Al-Tamimi, A.; Lewis, F.
