Abstract: For radial magnetic bearings with the configuration of
multi-pole, independently driven coils, a fault-tolerant control scheme
is developed on the basis of the method of generalized bias current
linearization and controller reconfiguration. The Scheme is applicable
to radial bearings with different magnet pole geometries by taking into
consideration the coupled effect of magnetic flures. Simulation results
are provided to show the feasibility of the above scheme.
