The purpose of this paper is the application of some existing techniques for the modelling and regulation of an eddy current brake process. An approximate theoretical model is derived for the behavior of an eddy current disc brake in the low-speed zone. Input-output information is used to obtain a polynomial state-affine behavior model for such a process. Dynamic and static feedback compensator schemes are proposed for the process speed control in the presence of unknown braking resistant torque. The dragging torque value is estimated by an appropriate nonlinear observer. Experimental results are presented.

## Abstract We present a systematic study of how to take into account external excitation in the eddy current model. Emphasis is put on mathematically sound variational formulations and on lumped parameter excitation through prescribed currents and voltages. We distinguish between local excitation
The aim of this paper is to analyze a finite element method to solve the eddy currents model in a bounded conductor domain. In particular we study a weak formulation in terms of the magnetic field. In order to impose suitable boundary conditions from a physical point of view, we introduce a Lagrange
