Claim 7:
8. A system for drilling a well, the system comprising:
a top drive operable to rotate a drill string and a drill bit;
a downhole sensor positionable within the well and operable to detect stick-slip vibrations of the drill string at a frequency of the stick-slip vibrations caused by the rotation of the drill string and the drill bit; and
a drill bit sensor operable to detect at least one of a rotational speed of the drill bit, or a torque of the drill bit;
a control system in electronic communication with the top drive, the control system comprising a processor programmed to
adjust the control system based on a determined reflection coefficient of the drill bit for the frequency based on at least one of a rotational speed of the drill bit or a torque of the drill bit and a reflection coefficient of the top drive for the frequency based on at least one of a rotational speed of the top drive or a torque produced by the top drive to adjust the operation of the top drive to reduce or eliminate stick-slip of the drill string.
