METHOD FOR ADAPTIVE CONTROL OF AN ELECTROMECHANICAL SYSTEM WITH A HARMONIC LOAD MOMENT IN A WIDE RANGE OF SPEEDS AND APPARATUS FOR IMPLEMENTATION THEREOF Russian patent published in 2021 - IPC G05B11/01 H02P7/00 

FIELD: controlling.

SUBSTANCE: group of inventions relates to the field of controlling electromechanical systems. The method consists in studying the spectrogram of the speeds of the electromechanical system, isolating the frequency of the most significant agitation, calculating the polynomial forming the mathematical model of agitation, and introducing said polynomial as a factor into the denominator of the transfer function of the adjuster, and synthesising feedback coefficients, at the first stage of configuration of the transfer functions of the elements, the coefficients of the polynomial of the transfer function of the internal adjustment circuit are found, and at the second stage, the polynomial of the adjuster of the external circuit is formed based on the speed of the working body, accounting for the set speed of the system, wherein the structure of the adjuster of the external circuit, containing the model of agitation, is implemented in the combined canonical observability form. The apparatus comprises an adjuster, a power converter, a direct current electric engine, a first and a second comparison elements, three inertia-free voltage, current and speed feedback links, a quad splitter, an e₁ calculation unit.

EFFECT: increase in the stability in a wide range of speeds.
