METHOD FOR CONTROLLING SYNCHRONOUS ELECTRIC MACHINE Russian patent published in 2022 - IPC H02P6/08 H02P21/06 H02P21/22 

FIELD: car industry.

SUBSTANCE: group of inventions relates to a device for controlling a synchronous engine. A method for controlling a synchronous three-phase electric machine containing a stator and a rotor consists in measuring currents of the first and the second phases of the mentioned stator, measuring an angular position of the rotor, calculating the mentioned currents measured in a rotor frame of reference (d, q), calculating an error rate of automatic control, recursively calculating compensation voltages of current harmonics, calculating control voltages for the electric machine, and supplying control voltages to the electric machine. In this case, calculation of control voltages is recursively performed in the specified rotor frame of reference (d, q) and in the form of dependence on the value of a control update period, value of DC voltage (V_DC) and electric angular rate of the rotor. A device for controlling a synchronous three-phase electric machine, an electric system containing a synchronous electric machine and a control device, and a vehicle containing an electric system are also claimed.

EFFECT: providing the elimination of a static error rate, good performance in a transition mode, and efficient compensation of anti-electromotive force effects.
