Abstract
A position sensing system for measuring a position of a moving object includes a first magnetic sensor configured to measure an intensity of a magnetic field produced by the moving object. The system includes a controller configured to estimate a position of the moving object based on a nonlinear model of the magnetic field produced by the moving object as a function of position around the moving object, and based on the measured intensity of the magnetic field produced by the moving object.
