Active Vibration Suppression by the Receptance Method: Partial Pole Placement, Robustness and Experiments

The receptance method in active vibration suppression is presented. Robust eigenvalue assignment is achieved by selecting controller parameters that not only place the eigenvalues at desired locations but also minimize the sensitivity of the eigenvalues to measurement uncertainty. Partial pole placement is demonstrated experimentally, in which case certain closed-loop eigenvalues are assigned while others are deliberately selected to be unchanged by control action.
