Abstract :
The presented paper shows how nonlinear control theory can be applied to magnetic bearings with permanent magnetic force. Because of the difficult expression for the magnetic force symbolic computation of Lie derivatives becomes unhandy. Therefore the Lie derivatives will be calculated applying automatic differentiation.
