2.2. Modelling of the active magnetic bearing actuator
Active magnetic bearing is an archetypical electromagnetic system where the
electrical and mechanical energies are conjugated by the magnetic field. A dynamic
representation of the active magnetic bearing in y-axis is governed by the assortment of
ordinary differential equations:
u 1 = R 1 i1 + L d 1

u 3 = R 3 i3 + L d 3
