Current Compensation Controller with Disturbance Acceleration Observer in Bearingless Motor
In order to improve the suspension performance of bearingless motors, the disturbances could be not neglected and some measures should be considered in the design of the controllers. In this paper, a disturbance acceleration observer is adopts based on the suspension model of the consequent-pole permanent magnet bearingless motor. And a suspension current compensation controller is proposed with the observer. In this case, an equivalent disturbance-current is utilized to compensate for the suspension current component caused by the disturbance displacement. Simulations are carried out with several kinds of displacement disturbance sources. The results demonstrate the validity of the proposed controller.
