The data has the following strcture:

The .mat file contains 2 variables: targeted and data_messung
- targeted only contains the meta data of the measurements which we aimed for (start/end rotor speed, measurement time, etc.)
- data_messung contains the measurement data

The data is listed in the matrix data_messung.data. Note that we use the coordinates y and z in the publication.
The test-rig uses the coordinates x and y instead. We use the convention of the paper here.

We have saved differemt signals for the active control experiments than for the passive run-out and the system identification experiments.
The data of signals which are not always recorded are not used for the publication.

The columns correspond to the following data (for active control experiments):

1. Rotor speed; 
		Differentiation of the current angle with and an additional moving average for smoothing which 
		causes a time delay. We used an offline filter to estimate the current rotor speed for the 
		publications which negates this time delay

2. Encoder index;
		Index of the encoder from 0 to 1999; You can map 0 to 2 pi to the index. This is used to compute the 
		instantanous angle of the rotor

3. Displacement in mm of Disc 1 in y-direction without runout compensation;
