A drive system (10) comprises at least one electrical machine (12) and a plurality of rotating components (14), which are interconnected via shafts (18, 20, 22). A method for damping torsional oscillations in the drive system (10) comprises: determining angular speeds (θi) for at least one of the shafts (18) based on measurements in the drive system (10); determining a damping torque (Tdamp) from the angular speeds (θi) with a function that models at least some of the electrical machine (12), the rotating components (14) and the shafts (18, 20, 22); adapting a reference torque (Tref) for the at least one electrical machine (12) by adding the damping torque; and controlling the at least one electrical machine (12) with the adapted reference torques (T).
