An electric axle assembly for a motor vehicle includes an electric machine suitable for operating as a motor, an axle for transmitting a power delivered by the electric machine to wheels of the motor vehicle, a transducer configured to detect an error variable representative of one or more parameters identifying a first vibration caused by an operation as a motor of the electric machine controlled by a control input, and a control unit configured to acquire the error variable detected by the transducer, determine one or more variable parameters of an adaptive model to compute a correction input to be superposed to the control input to update the control input, determine the correction input using the adaptive model defined with the determined variable parameters, and control the electric machine with the updated control input by superposing the correction input to the control input.
