Abstract :
The dynamic behavior of the discussed radial active magnetic bearings is analyzed using a finite element-based parametrization coupling model. Numerical calculations of the open-loop controlled and the closed-loop controlled system are performed. The results presented show that the magnetic nonlinearities and cross-coupling effects deteriorate the overall system performances.
