The simultaneous optimum design of structural and H∞ control system is a complex and multiobjective optimization problem. It is very important to select an appropriate objective function in order to obtain a superior design. In this paper, an objective functions is proposed in the case of simultaneous optimum design to derive a better design than in the case of individual optimum design. In this method, every objective function is normalized in order to unify the available range of each objective function. Using this method, all objective functions, which are related to the structural and control objective functions, can be estimated equally. In the numerical example, simultaneous and individual optimum design have been carried out. It is shown that a better design can be obtained using the proposed objective function in the case of simultaneous optimum design than in the case of individual optimum design.
