DEVICE FOR CONTROLLING ROTATING ELECTRICAL MACHINES Russian patent published in 2019 - IPC B60L15/20 B60W10/08 B60W30/20 B60K6/485 B60L50/60 H02P29/00 

FIELD: machine building.

SUBSTANCE: invention relates to devices for traction system control for vehicles with electric traction. Control device for rotary electric machine of vehicle includes filtration processor, controller, module of parameters calculation, module of variable setting. Filtration processor filters the target torque of the electrical machine so as to suppress the vibrating frequency component of the kinematic chain using a filter having a transmission frequency characteristic. Controller performs control of electric machine according to filtered target torque. Parameters calculation module calculates, according to the vehicle motion state, a parameter associated with the requested value for the response speed based on the output torque of the rotating electrical machine relative to the target torque. Variable setting module variably sets transfer frequency characteristic of filter so that to reduce degree of attenuation of vibration frequency component with increase of requested value for speed of response by output torque.

EFFECT: reduction of vibration frequency component at high speed of response when controlling torque of electric motor.
