Abstract:
A sensor system including a movable member, a sensor, and an interpolator. The sensor is configured to generate a first output signal and a second output signal. The first output signal has a first phase angle, the second output signal has a second phase angle, and a first difference between the first phase angle and the second phase angle has a first value. The first value of the first difference includes an offset related to a mechanical incompatibility between the sensor and the movable member. The interpolator is configured to receive the first output signal and the second output signal. The interpolator is operable to apply a compensation factor to generate a third signal having a third phase. The compensation factor has a value that is based on the mechanical incompatibility between the sensor and the movable member.
