Abstract
A method for controlling an electrical drive of an electrically driven air compressor of a motor vehicle and a corresponding control circuit. A prevailing load torque of the air compressor that is applied at a drive shaft of the compressed air compressor is estimated as a function of at least one operating parameter and is fed forward as an estimated disturbance variable to the control circuit of the electrical drive to reduce a control error produced as a result of the prevailing load torque.
