ABSTRACT:
A fault-tolerant control system for a magnetic bearing arrangement which maximizes dynamic response of the control system is disclosed. The arrangement includes a main digital signal processor responsive to rotor position/velocity signals to supply control signals to bearing control coils and a secondary digital signal processor responsive to accelerometer signals to provide open-loop vibration control for correction of mass imbalance of the rotor system. In addition, sources of vibration which have fundamental frequencies at some multiple of the rotor system rotational frequency can also be controlled.
