Unbalance Suppression for Active Magnetic Bearing Rotor System Based on Disturbance Observer
Aiming at the problem of co-frequency disturbance caused by mass imbalance in the AMB system, a dynamics model is established firstly, and then a composite controller based on the model is proposed, which combines a proportional differential (PD) and a disturbance observer (DOB). Finally, the simulation verified that the proposed method can have good robust control performance under the conditions of constant speed.
