Abstract : This volume documents the progress made in four principal areas during this reporting period: (1) The difficulties encountered in the Large Space Structure (LSS) system identification were studied. Focusing on the high-resolution identification problem, a procedure for identifying lightly damped, closely spaced modes is derived; (2) Two approaches to the incorporation of actuator dynamics and the role of actuator transducers in LSS vibration control were explored; (3) A modal dashpot/modal spring control design is presented, and (4) A controlled experiment for the ACOSS design is proposed in which each principal element in the overall synthesis process is systematically examined.
