Energy management by means of fault conditions on active magnetic bearing systems

Abstract

This paper presents the use of fault conditions on active magnetic bearing (AMB) systems as an energy management tool to improve the operation of AMB systems. Fault conditions on AMB system are broadly classified into external faults and internal faults, where external faults normally have some external disturbance acting on the system. These external disturbances will always have a transient component and possibly a steady state component. Internal fault conditions mostly refer to signal processing faults or failures. It can be seen that by analyzing these fault conditions, the operation of the AMB system can be improved. The use of fault condition on AMB systems therefore provides a valuable energy management tool
