Abstract :
A linear DC motor (LDCM) has been proposed as an actuator for the COFS I Mast and the COFS program ground test Mini-Mast. The basic principles of operation of the LDCM as an actuator for vibration suppression in large flexible structures are reviewed. Because of force and stroke limitations, control loops are required to stabilize the actuator, which results in a nonstandard actuator-plant configuration. A simulation model that includes LDCM actuator control loops and a definite-element model of the Mast is described, with simulation results showing the excitation capability of the actuator.<>
