Abstract

A position sensor measures a magnetic flux of a magnetic field produced by a magnet system in a first direction and a second direction. Values associated with the measured magnetic flux in the first direction are adjusted based on a first gain and a first offset that are determined based on the measured magnetic flux and a reference magnetic flux in the first direction. Values associated with the measured magnetic flux in the second direction are adjusted based on a second gain and a second offset that are determined based on the measured magnetic flux and a reference magnetic flux in the second direction. A position of the magnet system with respect to the position sensor at a given time may then be determined based on the adjusted values of the magnetic flux in the first and second directions at the given time.
