Abstract :
The constraints on eigenvalue assignment imposed by various suggested schemes for controlling rotor vibrations are examined. The work is extended to consider oil-whirl instability which is met in many practical situations. A method is presented for avoiding this phenomenon for the case of a rigid rotor supported on oil-film journal bearings.
