A motor-generator system comprising an internal combustion engine, a motor-generator in driven engagement with the internal combustion engine by an endless belt, the motor-generator, a controller detecting a speed signal of the internal combustion engine, a driver input signal, a battery state signal and a motor-generator signal, the motor-generator operable to provide a motoring torque or a load torque to the internal combustion engine at a predetermined frequency according to a controller command, and the controller controlling the motor-generator torque at a frequency greater than 1 Hz such that when the internal combustion engine accelerates the motoring torque is applied to speed the motor-generator rotation and when the internal combustion engine decelerates the load torque is applied to slow motor-generator rotation such that motor-generator rotation is controlled to attenuate a system vibration.
