Abstract
The presented paper shows how nonlinear adaptive control theory can be applied to magnetic bearings. Here the backstepping formalism is used to derive a stabilizing control law, which guarantees stability in the sense of Lyapunov in the presence of a unknown load. The efficiency of the proposed method comparing to linear standard design (e.g. PID) is demonstrated through experimental investigations.
