%X This paper focuses on the integrated structural/control optimization of a large space structure with a robot arm and tip payloads subjected to the gravity-gradient torque. Constraints from the structure and control disciplines are imposed on the integrated optimization process with the aim of obtaining the structure's minimum weight and the optimum control performance. The result demonstrates the feasibility to solve the problem by taking into account combined constraints from the separate disciplines, structures and control. Further, the resulting minimum structural weight represents a aving of about 20 with respect to the weight of the initial given structure while the control design accomplishes the objectives of suppressing and controlling the structural vibration and attitude without violation of the control damping factor imposed on the problem.
