✦ Synopsis

This paper considers cibration control of a single massJle.uible rotor on damped flexiblesupports with actitiefeedback control. Both proportional and dericaticefeedback control are utilized. Free cibrations and unbalance response of the rotor-control system are determined. The effect oJ,f'proportional control is to increase the critical speed of'rotating machinery while the effect of dericatiue control is to reduce the amplitude of cibration. Generally larger ratios of support sttjness to shaft stiffness require larger calues of control parameters to produce given awtplitudes of vibration. ivomenclature
