Abstract
A device for determining a first angle between a rotor and a stator, having inputs for reading amplitudes of electrical signals detected via a sensor system and representing a first angle, wherein the device has an angle estimator for estimating a second angle, the device determines amplitudes representing the second, estimated angle, the device has at least one controller with which at least one difference between the first angle and the second, estimated angle can be minimized, and the second, estimated angle can be provided via an output.
Claims12
A device to determine a first angle between a rotor and a stator, the device comprising:
- at least one input for reading an amplitude of an electrical signal detected via a sensor system and representing a first angle;
- an angle estimator to estimate a second angle;
- an ascertainer to ascertain an amplitude representing the second, estimated angle;
- at least one controller via which at least one difference between amplitudes representing the first angle and amplitudes representing the second, estimated angle is minimized;
- and
- an output to provide the second, estimated angle.
