Recent advances in the field of control theory have enabled us to design active vibration control systems for various large-flexible structures. In many cases, the controller used to achieve vibration suppression has been synthesized for the given mathematical model of the structure. The control system designer has not been able to utilize the degree of freedom to adjust the structural parameters of the control object. To overcome this problem, some studies are now using on the so-called "Structure/Control Simultaneous Optimization" method, which involves a numerical optimization technique. In this paper, we parametrize all controllers to optimize the structure and control systems simultaneously and show that these controllers have a special form of a decentralized-type controller. In this framework, a criterion is given to judge whether the result of the optimization is valid from the viewpoint of the energy needed to achieve the desired closed-loop performance. Using this concept, a constrained optimization problem is formulated and solved numerically.
