A method comprises: applying, by a motor controller of an electric motor, a bandpass filter to a signal from a sensor on a rotor of the electric motor, the signal indicating rotational speed of the rotor to detect a torsional oscillation or vibration in a driveline of the electric motor to be attenuated; providing the filtered signal to a proportional derivative controller configured for disturbance rejection; generating, by the proportional derivative controller, an attenuation signal for attenuating the torsional oscillation or vibration in the driveline; combining the attenuation signal with a driver torque command signal to produce a combined torque command signal, the driver torque command signal indicating an amount of torque requested from the electric motor; and producing torque with the electric motor based on the combined torque command signal.
