Abstract
We investigate the relationship between the parameters of a proof-mass actuator and the performance of that actuator within a vibration suppression loop for a flexible structure. We parameterize the model of the actuator in terms of the length of the proof-mass, the mass of the proof-mass, and the saturation force of the electromagnetic subsystem. The performance of the actuator within a vibration suppression control loop is characterized in terms of the relationship between the parameters and the structure's natural frequency. These results can be used to size a proof-mass actuator to maximize the operating region of the actuator and to maximize the ratio of the mass of the proof-mass to the total mass of the actuator .
