The algorithm of resonant fluctuations amplitude stabilization of dynamically counterbalanced drilling string on carrying cable with swinging movement of jackbit is developed. Imitating modeling of the resonant asynchronous electric drive with swinging movement of jackbit with the frequency converter in various operating modes is resulted.
The laboratory experimental stand for research of the asynchronous resonant electric drive on a physical breadboard model of dynamically counterbalanced drilling string is developed. The asynchronous electric drive with swinging movement the autoresonant oscillation mode is realized.
Imitating modelling the resonant electric drive of return-rotary movement (RRM) for dynamically the counterbalanced chisel shell with algorithm of a direct torque control (DTC) is lead. The control system is developed. Results of modelling opened and closed electromechanical systems (EMS) are resulted.
