Abstract EN
Active magnetic bearings consume much less power than conventional passive bearings, especially when power-minimizing controllers are employed.
Several power-minimizing controllers have been proposed, such as variable bias controllers and switching controllers.
In this paper, we present an appraisal of the power-minimizing control algorithms for active magnetic bearings in an attempt to provide an objective guideline on the merits of the control algorithms.
In order for the appraisal, we develop an unified and consistent model of active magnetic bearing systems.
The performances of the power-minimizingcontrollers are assessed through this model.
The results show that the power-minimizing controllers indeed save considerable power when the machine state is relatively steady.
However, a simple proportional-derivative type controller is on a par with the much morecomplex power-minimizing controllers in terms of power consumption when the machine is experiencing transient loads.
