FIELD: electricity.SUBSTANCE: invention proposes an adaptive compensation method of influence of harmonic oscillations of moment of load in an electromechanical system and a device for its implementation. The method consists in investigation of a spectrogram of speeds of the electromechanical system, separation of frequency of the most sufficient disturbance, calculation of a polynom forming a mathematical disturbance model, and introduction of this polynom by a multiplier to a denominator of a transfer function of a control, and synthesis of feedback coefficients, with that, coefficients of polynoms of transfer functions of the control and an out-of-contour shaper are changed depending on the current speed of the working element. The device includes an out-of-contour shaper, a control, a power converter, a DC electric motor, the first and the second comparison elements. Besides, it includes three inertia-free links of feedbacks as to voltage, current and speed, a divider, a quad unit, evaluation unit e, evaluation unit e, and evaluation unit e.EFFECT: improving control process accuracy.2 cl, 6 dwg |
