Abstract
The present invention provides a control circuit () and a method for checking the plausibility of a rotor position angle. The control circuit is designed with: a rotor position angle determination device () for determining a first rotor position angle, φ(t), at a first time, t, and at least one second rotor position angle, φ(t), at a second time, φ, before the first time, t; a computing device () for determining a rotor position angle,(t), to be expected at the first time, t, from a computational model of the computing device () using at least the second rotor position angle, φ(t); and a plausibility-checking device () for outputting a signal () which indicates the determined first rotor position angle, φ(t), as plausible if an amount of a difference between the rotor position angle,(t), to be expected and the determined first rotor position angle, φ(t), does not exceed a predetermined threshold value.
