MAGNETIC BEARING AND METHOD TO BUILD CONTROL MODELS FOR MAGNETIC BEARINGS

摘要

In a state where part of a plurality of electromagnets (27) is controlled based on a control model built in advanced for a first control region (A1), and where position control of a drive shaft (13) is performed by controlling one or a group of the electromagnets (27) in a second control region (A2), an electromagnetic force of the electromagnets (27) controlled within the second control region (A2) is calculated based on an electromagnetic force of the electromagnets (27) controlled within the first control region (A1).
