Abstract:
A method for controlling a rotation rate of an electric motor includes the s following steps: determining if an absolute value of a difference between an objective rotation rate of the electric motor and an actual rotation rate of the electric motor is greater than or equal to a predetermined value, and if yes, compensating a q axis current of the electric motor to adjust the rotation rate.
