Failure of drill-strings is very costly in terms of money and time and occurs more frequently than oil companies would like to see. There are many reasons for drill-string failure, such as vibration, fatigue, and buckling. This paper addresses the problem of suppression of stick-slip oscillations in oil well drill-strings using proportional integral derivative (PID) and lead-lag controllers in conjunction with genetic algorithms. Simulation results are presented to validate the proposed control schemes. 12 Journal of Canadian Petroleum Technology 48 ARTICULO Karkoub, M. 43116 Abdel-Magid, Y.L. 43117 Balachandran, B. 43118 171294 171294 0 0 0 0 239113 BAAB BAAB 2026-03-05 200046153 0 200046153 2026-03-05 15:13:41 2026-03-05 ARTICULO
