Suppression of Drill-String Stick-Slip Vibration [PDF]

MATEC Web of Conferences, 2018
We investigate experimentally and numerically suppression of drill-string torsional vibration while drilling by using a sliding mode control. The experiments are conducted on the novel experimental drilling rig developed at the University of Aberdeen [1]

Stick–Slip Vibration Characteristics Study of the Drill String Based on PID Controller [PDF]

Energies, 2023
In order to address the issue of drill string stick–slip vibration, which leads to drill bit wear and reduces the drilling velocity, we conducted a study on the characteristics of stick–slip vibration using a proportional-integral-derivative (PID ...
