Abstract :
The coupling of magnetic paths of SPMB (Six-Pole Magnetic Bearing) is strong. This article introduced two control strategies for it according to coordinate transform principle in motor control theory. This two strategiespsila releasing coupling control are analyzed and validated from magnet paths, and this two strategiespsila characteristics were compared. Finally one high reliability control strategy is validated based on six power amplifier control strategy.
