This paper analyses a control mechanism designed to signiยฎcantly ameliorate the sustained excitation of torsional relaxation oscillations (slipยฑstick) due to frictional torques generated by an active bit during drilling operations with an extended drill-string. The proposed mechanism of torsional re
