This paper presents a new modeling method and a control system design procedure for a flexible rotor with many elastic modes using active magnetic bearings (AMBs). The purpose of our research is to rotate the rotor for passing through the 1st and the 2nd critical speeds caused by flexible modes. To achieve this, it is necessary to control motion and vibration of the flexible rotor simultaneously. The new modeling method named as Extended Reduced Order Physical Model is presented to express its motion and vibration uniformly. Meanwhile, to solve problem as controllability and observability when elastic rotor is supported at both ends, location of AMBs and the shape of the rotor are modified. Moreover, phase-lead compensator is put to improve stability of experimental equipment and its effect verification is carried out by simulation.
