DEVICE FOR ELECTROMECHANICAL SYSTEM MANAGEMENT Russian patent published in 2018 - IPC G05B13/02 H02P7/00 H02P29/50 

FIELD: electrical engineering.

SUBSTANCE: invention relates to a control system for automated electric drives. Above device for controlling the electromechanical system comprises a first reference element, controller, second reference element, power converter, measuring unit, inertia-free speed feedback link with transmission factor K1, inertia-free current feedback unit with transmission factor K2, non-inertial voltage feedback link with transmission factor K3, feedback unit, amplifier and integrator unit. Wherein the first output of the measuring unit is connected to the input of the feedback unit. And the main output of the feedback unit is connected to the inverting input of the first reference element. And the output of the first reference element is connected to the driving input of the integrator block, whose feedback m-inputs are connected to the corresponding m-outputs of the feedback unit. And the output of the integrator block via an amplifier, whose gain is 1 / fn, is connected to the non-inverting input of the second reference element and to the input of the controller, n + 1 outputs of which are connected respectively to n + 1 control inputs of the integrator block, with m≥n.

EFFECT: influence of harmonic oscillations of the load moment for controlling the electromechanical system is reduced.
