The PID controller with an analog circuit is ofen used in the active magnetic bearing system. Although this system is simple and nonexpensive, the vibration control for a flexible rotor is not sufficient. For the purpose of improving the modal damping of the mechanical system, the state feedback control scheme with dynamic observers is presented. The design of an estimator whose state elements consist of the modal coordinate and unbalanced force is based on a simplified reduced-order model of the mechanical system. This concept is applied to the experimental system of a flexible rotor suspended by an active magnetic bearing, and it is confirmed by measurements and numerical results that its capability to improve modal damping is superior to ordinary PID control.
