DEVICE FOR ELIMINATION OF INFLUENCE OF HARMONIC PERTURBATIONS OF LOAD MOMENT IN ELECTROMECHANICAL SYSTEM Russian patent published in 2018 - IPC G05B11/01 H02P7/00 

FIELD: electronics.

SUBSTANCE: invention relates to the controls and can be used in controlling parameters of complex electromechanical systems, for example, DC and AC electric drives. Device for eliminating the influence of harmonic disturbances of the load moment in an electromechanical system contains an out-of-circuit driver connected to a non-inverting input of the comparison element, the output of which is connected to the regulator of the external circuit, a power converter connected to a direct current motor connected to the input of the measuring unit, the output of which is connected by speed feedback with the inverting input of the comparison element. Device also comprises an internal circuit controller, the second out-of-circuit driver, the second comparison element. Output of the external circuit controller via the second out-of-circuit driver is connected to the non-inverting input of the second comparison element, to the inverting input of which the output of the measuring unit is connected, the output of the second comparison element is connected to the input of the internal circuit controller connected to the input of the power converter. Regulator of the external circuit is made taking into account the integral component of the perturbation model, the regulator of the internal circuit is made taking into account the oscillatory component of the perturbation model and is tuned to the speed of 5-7 times higher than required from the system.

EFFECT: as the result, dynamic accuracy improves, hardware and software costs are reduced along with the technical implementation of the system.
