Analysis and design, modelling and simulation, exact lin earization, LQ control.


The controller design for the magnetic bearing is described. This control design is carried out by compensating the non linearity by finding an approximation of the nonlinear de pendence and then by finding an inverse function of this approximation. As the nonlinearity cannot be described precisely the controller has to be robust enough. The re sults are demonstrated on a various simulations.
