The objectives of this experimentally and to simulate study were to implement theoretically a method of active vibration control, known as modal-space control, on a relatively simple beam-cable structure. The control was implemented in analog form and provided modal viscous damping in each of the three modes of the structure. Transient response to initial conditions was analyzed experimentally and theoretically. Control hardware included permanent magnet-coil systems for the three control force actuators and the single velocity sensor, and an analog controller built around integrated circuit operational amplifiers. This thesis compares open-loop experimental response and closed-loop experimental and theoretical response on the basis of Fast Fourier Transforms of transient time data. / M.S.
