Are you considering passive radial bearing with active axial, or other way around? Or have I got wrong end of the rabbit?
Problem I see is passive magnetic systems like in a pair of radial bearings need to be stabilized with great precision axially. This is often done with jewel bearings and the axial loading is small. To do this with a active control system would be extravagant.
Active systems are used with pm bearings in Halbach arrays for levitation.

Passive radial bearing is to get magnetic damping
the electromagnets are here just tu control the repulsive force between the magnets.
The mobile part (magnet ring) have te be centred.
RE: Semi active magnetic bearing
what i'm looking for is the electronic circuits for this type of system

you say semi- active. This implies changing the passive elements actively.
I think you want to actively control the MBs. You would need to design a nice little control system for it. This has been done before. Look up maglev systems.
