Claim 19:
20. The non-transitory computer readable medium of claim 14, wherein the method further comprises:
detecting stick-slip vibrations over a range of frequencies via the downhole sensor;
determining the reflection coefficient of the drill bit for each frequency of the range of frequencies based on at least one of the rotational speed of the drill bit or the torque of the drill bit;
determining the reflection coefficient of the top drive for each frequency of the range of frequencies based on at least one of the rotational speed of the top drive or the torque produced by the top drive; and
adjusting the control system such that |rb(s)·rd(s)|<1 for each frequency of the range of frequencies.
