The controller of active electromagnetic bearings which enables to cancel out external forces is effective for reducing vibrations of a flexible rotor. It is very time-consuming to estimate external forces by an observer or an inverse system even if using digital signal processor. Therefore it seems to be difficult to apply this control to high speed spindles. In this paper, considering that estimation has not to be real-time in case that external forces are sinusoidal, we design the digital controller which cancels out unbalance forces under relatively short sampling period using previously calculated unbalances. Simulating unbalance responses of an flexible rotor system, we find out that for reducing resonance vibrations this control is superior to the PID control.
