METHOD FOR AUTOMATIC COMPENSATION OF INFLUENCE OF HARMONIC OSCILLATIONS OF LOAD MOMENT IN ELECTROMECHANICAL SYSTEM AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2016 - IPC G05B11/01 

FIELD: electromechanics.

SUBSTANCE: invention represents a method of automatic compensation of influence of harmonic oscillations of moment of load in electromechanical system and device for its implementation relate to electromechanics and can be used in designing of automated electric drives of direct and alternating current. Method consists in analysing of spectrogram of speeds of electromechanical system, separation of frequency of the most sufficient disturbance, calculation of a polynom forming mathematical model of disturbance, introduction of this polynom as cofactor in the denominator of controller transfer function, synthesis of controller coefficients and internal circuit feedbacks. Device contains external generator, controller, power converter, DC motor, measuring unit, first and second comparison elements. Besides, it includes three fast-response feedback links by voltage, current and speed.

EFFECT: technical result consists in reduced hardware or software costs related to technical implementation of the system.
