Magnetic field analysis of nonlinear system considering both motion and voltage equations

This paper describes the method that makes it easy to simulate the magnetic levitation system by using the boundary element method (BEM) or the hybrid finite element (FE)-boundary element (BE) method. The proposed approach enables the simulation a nonlinear control system with consideration of both the motion equation and the voltage equation. The voltage equation contains the term of the leakage inductance that has to be considered in the actual model.
