磁轴承
摘要：
在磁轴承中设置了控制部(30)，该控制部按照在电磁铁(27)之间关于下述变量中的两个以上变量间的相关关系的个体差将控制区域分为两个，在个体差较小的第一控制区域(A1)中利用各个电磁铁(27)共通的控制模型对驱动轴(13)进行位置控制，在个体差较大的第二控制区域(A2)中利用针对各个电磁铁(27)或者规定数量的每组电磁铁组设置的控制模型对驱动轴(13)进行位置控制，所述变量为在电磁铁(27)中流动的电流(i)、磁通匝链数(ψ)、间隙(G)、磁能(Wm)、磁共能(Wm’)、电磁力、以及利用电流(i)、磁通匝链数(ψ)、间隙(G)、磁能(Wm)、磁共能(Wm’)、电磁力导出的变量。
摘要（英）：

A control unit (30) divides a control area in two depending on individual differences between electromagnets (27) with regards to correlations between two or more of current (i) flowing in the electromagnet (27), interlinked magnetic flux, gap length (G), magnetic energy (Wm), magnetic co-energy (Wm'), electromagnetic force, and variables derived by using these, and controls the position of a drive shaft (13) by using a common control model for electromagnets (27) in a first control area (A1) in which the individual differences are smaller and by using a control model provided for each electromagnet (27) or for a prescribed number of electromagnet groups in a second control area (A2) in which the individual differences are larger.
