Abstract

The greatest shortcoming of magnetic position sensor systems is their sensitivity to fabrication tolerances. In this work, we propose a novel calibration scheme based on evolutionary optimization and the analytic solution for the magnetic field. This method allows us to calibrate more than 10 degrees of freedom in the course of seconds with little computation requirements, and realize a complex, novel position system by simple means.
