Abstract
A magnetic bearing system includes a rotor with a plurality of masses distributed along the shaft including a portion having a circular peripheral surface suspended radially from pole pieces of permanent and electromagnets. A fault tolerant adaptive system responds to detected parameters of the rotor for varying the stiffness and damping the rotor. Position and speed of rotor are sampled at a rapid rate for each of a plurality of control axes and are processed independently during each sampling period. Malfunction of any of the processors causes supervisory controller to reconfigure the processing of the samples.
