摘要:
The disclosure relates to a method for operating a steering system, wherein the steering system has at least one electrical three-phase machine, at least one control circuit for actuating the electrical three-phase machine and at least one compensation device, which is operatively connected to the control circuit, for reducing a torque ripple of the electrical three-phase machine, wherein at least one compensation parameter of the compensation device is determined. It is proposed that during the determination of the at least one compensation parameter, at least one operating variable correlated with a pre-commutation angle of the electrical three-phase machine and/or with a supply voltage of the electrical three-phase machine is taken into consideration.
