Abstract :
A number of control system experiments were carried out during 1990 and 1991 on two contrasting flexible space structure facilities. The first facility is the JPL/AFAL flexible antenna in Pasadena, California. The second is the WPAFB/AFWL 12-meter cantilever truss in Dayton, Ohio. Each structure possesses a number of flexible modes of vibration which are lightly damped. The purpose of the experiments was to achieve active damping of the flexible modes via a digital control system. The control system designs were carried out using an H ∞-based technique of `weighted gap optimization´, which is closely related to Glover-McFarlane loop-shaping
