Abstract :
A nonlinear model of an axis of an active magnetic bearing is presented. An implicit nonlinear discrete-time controller based on a one-step prediction of the model evolution is then proposed to stabilize this model. Simulation results show the robustness of the proposed controller to perturbations and modelling errors
