In this paper, the controllability and observability of the attitude dyna-mics for a large communication satellite with flexible solar arrays is first discussed, and a simple condition of the controllability and observability is presented. Then, the higher order of the mathematical models is reduced by using order-reduction method of large scale system by aggregation. A design procedure using the LQG theory for reduced order control system is investi-gated. The robustness properties of the reduced order control system for system perturbation and the residual modes are analyzed by using the singular values of the matrices. It is shown that appropriate choice the feedback gain matrix and the observer gain matrix, the conrol spillover and observa-tion spillover of the residual modes can be suppressed in the reduced order control system. Method suggested is applicable to the general large space structure control problems.

As for the system in terms of structured uncertain description, this paper represents a robust design method. By this method, a function, which is associated with the robust stabil ity boundary, is selected as performence index. At the same time, the polo assignment is also considered, so that the system has desired dynamical performance. In this paper, the optimum feedback matrix F* and observer gain matrix L* can be found by optimization. The numer ical examples show that the robustness of the system can be greatly improved in this way.
