Sažetak
The paper presents the speed control system design and simulation verification of a petroleum drilling system aimed at effective suppression of drill-string torsional vibrations in legacy drilling drives featuring mature series-wound direct-current motor drive technology. The vibration suppression system is based on the external damping feedback loop using a straightforward low-pass filter-based drill-string torque estimator and a reference correction term in the motor speed target path, with the motor speed feedback control system featuring a proportional-integral controller tuned for stiff disturbance rejection. The control system design is based on the damping optimum criterion, which results in straightforward analytical expressions for controller parameters. The effectiveness of the proposed control strategy is verified by means of comprehensive simulations.
