CONTROL DEVICE FOR ROTATING ELECTRIC MACHINES Russian patent published in 2018 - IPC B60L15/20 B60L11/18 

FIELD: machine building.

SUBSTANCE: invention relates to a control device for a rotating electric machine used in a vehicle. Vehicle is equipped with a drive chain. Drive chain includes a transmission for transmitting the output energy obtained from rotating the rotating link of the rotating electric machine to the driving wheel in accordance with a variable transmission factor. Control device contains: an extractor, a calculator, a controller and a suppressor. Extractor extracts, based on the rotational speed of the rotating link, a vibration component included in the rotational speed of the rotating link. Component of vibration is based on the vibrations of the drive chain. Calculator calculates the compensating torque to compensate for the vibrations of the drive circuit in accordance with the vibration component extracted by the extractor. Controller performs excitation control of the rotating electric machine in accordance with the compensating torque. Suppressor performs suppression to avoid changing the rotational speed of the rotating link due to a change in the transmission factor.

EFFECT: ability is achieved to prevent an excessive increase in the compensating torque, designed to reduce the vibrations received from the drive chain.
