FIELD: mining.
SUBSTANCE: method and control system includes the solution of one or more optimisation tasks containing the objective function. The objective function may depend on conditions including the physical model of the drilling system. The objective function can be minimized without resorting to the model, but by referring to the calculated hopping frequency based on the angular velocity profile of the drill bit. Additionally, actual downhole measurements for use in the method and control system, such as the angular velocity of the drill bit, can be calculated using an observation unit.
EFFECT: reducing or eliminating step-like supply and vibrations in the well.
