Abstract
In an electric steering device, a plurality of periodic disturbances (M(f), M(f), . . . M(f)) can occur which are to be compensated, while additionally occurring, in particular non-periodic, disturbances () are not to be compensated. So as to enable simultaneous compensation of a plurality of such periodic disturbances based on a model (G(s)) of the steering device, it is proposed to map the further disturbances Moccurring in addition to the disturbances M(f), M(f), (Mf) to be compensated, together with inaccuracies or modeling errors (Δs) of the model (G(s)) in the form of an unstructured disturbance ().
