Comparison of control oriented models for the long-stator linear synchronous motor and their experimental validation

In this paper, two control-oriented models for the long-stator linear synchronous motor are presented. One of them is based on lookup tables, generated offline by finite element analysis. The other one is based on the magnetic equivalent circuit method. Both models are derived from the motor geometry, magnetic characteristics of the involved materials, and the winding arrangement. Force ripple due to non-sinusoidal electromotive force (EMF), cogging forces and non-periodic characteristics of long stator linear motors are well simulated with these models. The intended application for these models is the design or improvement of the controllers, mainly for ripple force compensation. Results of both models were validated experimentally
