FIELD: mining.SUBSTANCE: method contains the following stages: (a) damping of sticking-slipping oscillations using a drilling mechanism above a drilling string, (b) control of drilling mechanism speed of rotation using a PI controller, (c) turning of a PI controller so that the drilling mechanism absorbs a larger part of twisting energy from the drilling string at the frequency of sticking-slipping oscillations or near it.EFFECT: tuning of proportional-integral or proportional-integral-differential controller for damping of twisting waves energy at sticking-slipping frequency or near it.21 cl, 8 dwg |
