This paper considers the derivation and application of closed loop vibration controllers that are designed for attenuation of multiple discrete frequency rotor vibration components. The component complex amplitudes are evaluated in real-time and used for dynamic feedback control with frequency matched control signals. Gain matrices are derived from on-line identification routines, performed under a finite set of different operating conditions. Controller gain matrices are synthesised using linear matrix inequality existence conditions for closed loop system stability and performance. Thus, the controllers can be designed with a degree of robustness to changing/non-linear dynamics. Implementation and testing is undertaken on a flexible rotor/magnetic bearing test rig. The controllers are shown to simultaneously attenuate vibration due to direct rotor disturbance forces and other indirectly forced non-synchronous frequency components.
