This research proposes a novel disturbance suppression method for hybrid magnetic bearings (HMB). By constructing a cascaded reduced-order extended state observer, the proposed approach achieves precise estimation and feedforward compensation of motor startup-induced disturbances in the magnetic bearing system, thereby significantly enhancing rotor levitation stability.
