Drill-string setup

Stick-slip vibrations are a well-known issue in drilling industry, these vibrations decrease the performance and reliability of drilling systems and accelerate bit wear. The drill-string setup in the DCT lab is a scaled version of a model of a real drilling rig. The setup is used to test and experimentally validate controllers that are being developed in the project on design and implementation of controllers in oil-field drill-string systems for rate-of-penetration increase. These controllers focus on the elimination of torsional stick-slip vibrations of the drill-string system, while using only measurements obtained at surface.
