The presence of harmful stick-slip oscillations in oil well drillstrings has attracted the attention of the control community in recent years. We show that the resulting feedback system of the proposed law is globally asymptotically stable. Simulations showing the typical response profiles obtained from the control algorithm designed are also presented.
