It was shown in an earlier paper that the authors’ recursive open loop adaptive control strategy can be used as the basis for an adaptive multi-objective control strategy to satisfy design criteria for rotor-bearing systems involving the relative weighting of forces transmitted to the foundation and rotor vibration. This paper describes a complementary-layer adaptive control strategy to limit vibration at critical locations along the rotor, where contact may occur, following changes in operating conditions, e.g. transient disturbances. Experiments are presented to explore the effectiveness of this approach.
