Tests of the controllers settings for a 5-phase permanent magnet tubular linear motor using Matlab/Simulink software

Abstract

The mathematical and physical models of the permanent magnet tubular linear motor (PMTLM) including control and supply system are presented in the paper. In the analysis a field-circuit model is used. The field model is calculated using the finite element method (FEM), while the circuit model is implemented in Matlab/Simulink software. The control algorithm as well as the graphical user interface (GUI) have been developed in the Matlab/Simulink package using the extended toolboxes. The controller uses a Texas Instruments digital signal processor (DSP) TMS320F2812. Data transfer is realized using the LPT port supported by the Real Time Workshop. Thus, it is possible to compare the results from the numerical model with the measured ones. A good conformity is obtained.
