A study is presented in which the vibrations of a rotor are controlled under both synchronous and transient conditions. A Fourier decomposition of the rotor vibration during successive synchronous cycles is performed and the fundamental amplitude component is monitored. An analysis of the component response is developed and a strategy is proposed for the rotor vibration control. This is based around a gain matrix derived for a steady-state open-loop controller and the loop is then closed in a form of generalized integral control using a single feedback parameter. Performance and stability characteristics are investigated and for a linear system it is shown that the control of transient vibration caused by sudden mass loss from a rotor is possible. Limitations are stated if the system becomes nonlinear. Multiprocessor hardware is used for on-line implementation of the controller algorithm to an experimental rig, consisting of a rotor supported by two journal bearings with a magnetic control actuator. The results show the effectiveness of the vibration control, which is evaluated over the stable operating range of the controller.
