Implementation and model verification of a magnetic levitation system

This paper presents the implementation of a two degree-of-freedom magnetic levitation system employing one permanent magnet linear synchronous motor, and the experimental validation of a mathematical model previously derived. The paper focuses on showing the development of a calibration procedure to estimate model parameters and its subsequent use for model verification. Experimental results show that the proposed mathematical model accurately describes the dynamics of the system over a wide operating range showing promise for the future implementation of nonlinear controllers.
