The experimental set-up for laboratory study of spacecraft control/ structural interaction have been designed. Design specifications have been derived, and all the actuators and sensors have been selected except the end- point displacement sensing of the arm. The mainbody and the flexible arm have been fabricated to meet design criteria. The equations of motion for the experimental model have been derived and natural frequencies determined. The natural frequencies of the flexible arm has been determined experimentally and compared with analytical predictions obtained by using the GIFTS finite element analysis program. The experimental and analytical results are in good agreement except the first mode.
