In the agricultural engineering field, the power take-off (PTO) shaft constitutes a crucial core element of the drive technology for external devices that can be connected to a tractor. For agricultural machinery manufacturers, it is therefore important to measure the performance of tractors and investigate the behavior of the tractor, especially its power take-off drive.

In collaboration with the industry partner CNH Industrial and the Institute of Electrical Measurement Technology, a PTO test rig should be improved. This testbench uses eddy current brakes for simulating a load for a tractor. The setup is to be captured through measurement techniques and regulated through a control loop to minimize the influence of disturbances.

Furthermore, a graphical interface is to be implemented to allow users to manually define predetermined load profiles. In addition to the practical aspect, a simplified model of the system is to be created to facilitate understanding of the functionality on a physical basis.
