Adaptive Control of Drill String Vibrations

Abstract

The basic principles and methods of drill string vibration control are studied. The prospects of development of a semiactive vibration damping method are shown. The principle of semiactive vibration damping developed by the authors using the Matlab Simulink graphical programming environment for modeling is studied. Analytical correlations of the equations of motion of this model are presented. Resulting motion graphs are derived and conclusions are drawn about the behavior pattern of similar vibration damping systems.
