Experimental Data for Fault Diagnosis in the Adaptive High-Rise D1244

<p>
<b>General information:</b><br>
This dataset is meant to serve as a benchmark problem for fault detection and isolation in dynamic systems. It contains preprocessed sensor data from the adaptive high-rise demonstrator building D1244, built in the scope of the <a href="https://www.sfb1244.uni-stuttgart.de/en/">CRC1244</a>. Parts of the measurements have been artificially corrupted and labeled accordingly. Please note that although the measurements are stored in Matlab's .mat-format (Version 7.0), they can easily be processed using free software such as the SciPy library in Python.

<b>Structure of the dataset:</b><br>
<ul>
<li><b>train</b> contains training data (only nominal)</li>
<li><b>validation</b> contains validation data (nominal and faulty). Faulty samples were obtained by manipulating a single signal in a random nominal sample from the validation data.</li>
<li><b>test</b> contains test data (nominal and faulty). Faulty samples were obtained by manipulating a single signal in a random nominal sample from the test data.</li>
<li><b>meta</b> contains textual labels for all signals as well as additional information on the considered fault classes</li>
</ul>
</p>

<p>
<b>File contents:</b><br>
Each file contains the following data from 1200 timesteps (60 seconds sampled at 20 Hz):
<ul>
<li><b>t:</b> time in seconds</li>
<li><b>u:</b> actuator forces (obtained from pressure measurements) in newtons</li>
<li><b>y:</b> relative elongations as well as bending curvatures of structural elements obtained from strain gauge measurements, and actuator displacements measured by position encoders</li>
<li><b>label:</b> categorical label of the present fault class, where 0 denotes the nominal class and faults in the different signals are encoded according to their index in the list of fault types in <code>meta/labels.mat</code></li>
</ul>
Faulty samples additionally include the corresponding nominal values for reference
<ul>
<li><b>u_true:</b> actuator forces without faults</li>
<li><b>y_true:</b> measured outputs without faults</li>
</ul>
Textual labels for all in- and output signals as well as all faults are given in the struct <b>labels</b>. Each sample's textual fault label is additionally contained in its filename (between the first and second underscore).
