Signal processing using Matlab and control toolbox for linear electrical machine modelling

This paper presents the method of filter design using Matlab, Simulink, and control toolbox. Further, a derivation of an armature circuit model is used to investigate the performance of a linear permanent magnet electrical machine. The armature circuit model is estimated through system identification techniques and digital filter technologies from the data of a 2D finite element model that is generated to determine the flux linkage map for a prototype made at Durham University. To explain the modelling process, in this paper, we demonstrate a Simulink model that includes a look up table for the 2D finite element model and digital filters. The models have been experimentally verified.
