Vibration of a flexible rotor is reduced by a quasi-modal control method with only velocity feedback. If a mathematical model includes much error of parameter identification, much cumulated error in feed back gains result from an incorrect equation of motion. In these cases, the responses with control are not improved as we expected, or the control system becomes unstable for the worst case. Therefore, in this paper, the control system is designed based on an experimental modal analysis instead of a mathematical model. The first mode to the fifth mode of the flexible rotor supported by linear actuators through bearing housings are controlled by only two sensors and two actuators in the experiments. The maximum amplitudes of unbalance responses are reduced, and the senf-excited vibrations caused by dry friction are prevented by the quasi-modal control.
