Purpose - The aim of this paper is to analyse the influence of various methods of controlling a stepper linear reluctance motor on the dynamic parameters of this motor. Design/methodology/approach - Construction, principle of working, and mathematical model of a four-band stepper linear reluctance motor are shortly discussed. In order to elaborate an effective tool for motor performance analysis, a circuital approach was applied. To increase model accuracy, major parameters of the model (main self- and leakage inductances) were calculated on the basis of a 3D electromagnetic field distribution using Finite Element Method (FEM). The nonlinearity of the core was taken into account. Elaborated mathematical model was implemented in MatLab-Simulink environment. Selected results of investigations are presented. Findings - The elaborated mathematical model and the review of control methods are very useful for analysis of dynamic operation of stepper linear reluctance motors. Originality/value - The paper provides a review of control methods of stepper linear reluctance motors.

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 fieldmodel is calculated using the finite element method (FEM), while the circuitmodel 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.

The coupled field-circuit model of a linear accelerator is presented in this paper. It is a three-stage construction. The fieldmodel was developed with using the finite element method (FEM). The circuitmodel was obtained by using basic principles in a variational (Lagrangian) form. The mathematical model has been compared with the physical one.
