ON-LINE COMPENSATION SYSTEM OF ROTOR MISALIGNMENT BASED ON AUXILIARY MAGNETIC BEARING

ON-LINE COMPENSATION SYSTEM OF ROTOR MISALIGNMENT BASED ON AUXILIARY MAGNETIC BEARING

Auxiliary electromagnetic bearing is introduced which could adjust the position of the rotor on-line with the current control of the active magnetic actuator. The additional vibration caused by misalignment is viewed as disturbance which could be auto identified and controlled on-line by using feedf...

description Auxiliary electromagnetic bearing is introduced which could adjust the position of the rotor on-line with the current control of the active magnetic actuator. The additional vibration caused by misalignment is viewed as disturbance which could be auto identified and controlled on-line by using feedforward learning control method. Finally the feedforward learning control approach is applied to a rotor bearing test rig with single disk. The experimental results confirm that the approach can correct the misalignment of rotor greatly.
