To improve accuracy of the plant model in control circuit simulation, you can create a lookup table (LUT) using the FEA calculation results for use in simulation.
JMAG-RT is a tool you can use to create data for use in a circuit/control simulator based on the FEA results by JMAG. On the other hand, you can also run a parametric analysis and arbitrarily create a lookup table from the results.
This document explains how to run parametric analysis in JMAG-Designer and register it as a lookup table for MATLAB.
