I am currently doing a project on positioning control of magnetic levitation system for my FYP.
However, I am facing a problem on my model.
When I connect it to microbox, I found out that the ball could not suspend in the air although giving the suitable voltage to hold it.
What should I do to make it run properly ? Or I need to write a C coding in M-file to run it with simulation ?
In magnetic levitation systems the CURRENT , not voltage in the coil determines the levitation force. A feedback is used, often with an optical position sensor, to balance the levitated object below the coil.

If I understand right, microbox doesn't provide a 2.9 A output, so you have an external power amplifier?
Supposed you achieve 2.9 A coil current and no sufficient electromagnetic action, it's not an electronical or control problem, isn't it? You'll want to check your magnetostatic design.
