Model Examples

Spatial Examples

The example shown below is for an accel/decel performed in the simulator with only longitudinal-control given to the pilot. The number of 'windows' in this case has been set quite high (50 windows) and the resultant output that can be seen shows good reconstructions for the pilot-gains. The top subplot seen on the figure is showing the original velocity input as well as a reconstruction (in red); the fit of the reconstruction is hardly visible because of it's closeness to the original data. The middle two subplots show the pilot gains; it is interesting to note the lack of activity of these gains during the accel-part of the manoeuvre. The final subplot shows the original and reconstructed pitch data.

The two gains that are produced relate to a feedback of distance to the pilot and a feedback of velocity to the pilot. The strong coupling between the two pilot gains should be noted.

Tau Examples

The two examples shown below are for flight test data provided by DLR. The tau data has been created and the coupling coefficient has been found between that and the tau-guide data. The coupling coefficient has then been used to recreate the velocity profiles.
