Abstract :
A linearized model of a self-sensing magnetic bearing used in a flywheel energy storage application is analyzed, and an intrinsic feedback mechanism is identified. Based on the model, a cascaded-loop controller is designed using a novel control design technique which actively rejects external disturbances, taking advantage of the feedback mechanism. Simulation results of force-disturbance rejection performance are presented.
