This paper describes theoretical and experimental work performed on the attitude and vibration control of a flexible space structure. Generally, the flexible space structure is composed of some modules with rigid couplers and has many vibration modes. Then, a dynamical model of the flexible space structure becomes generally too large for a controller designer to cope with, and it is difficult to get a useful reduced order model. We propose that the structure is composed of some modules with loose couplers. Then, since the interaction of the modules of this structure becomes small, we can treat each of the modules independently and design each controller by its low order model. Moreover, the damping of the vibration modes can be augmented by use of the colocated sensor/actuator pairs at the couplers. This approach is verified by physical experiments as well as numerical analyses and these results show good agreements.
