Abstract
A Hamiltonian model of an electromechanical actuator requires an approximation of its flux-current characteristic. It can be made using a piecewise affine function, based on sets of corresponding points in the spaces of flux and current. In the paper four original methods of constructing these sets based on measurements results are presented. The best results are obtained using methods that incorporate the computed value of the magnetic field coenergy in the modeled machine.
