Classification: CPC B  H | IPC B  H

Claim 9:
10. A steering system comprising:
at least one electrical three-phase machine;
at least one control circuit configured to actuate the at least one electrical three-phase machine;
at least one compensation device operatively connected to the at least one control circuit and configured to generate a compensation signal configured to reduce a torque ripple of the at least one electrical three-phase machine, the compensation signal provided to the at least one control circuit; and
a computing unit configured to determine at least one compensation parameter of the at least one compensation device based on a correlation of at least one first operating parameter with at least one of (i) a pre-commutation angle of the at least one electrical three-phase machine and (ii) a supply voltage of the at least one electrical three-phase machine,
wherein the at least one compensation parameter is used to generate the compensation signal, and
wherein the compensation signal is generated only when a vehicle speed is less than a predetermined speed limit.
