Adaptive Control of Drill String Vibrations [PDF]
Chemical and Petroleum Engineering, 2019 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.
