A novel multiobjective optimization formulation is presented for the combined structural and control design of flexible structures using several multiobjective optimization techniques. The quadratic performance index, control energy and structural weight are integrated into one single objective function for minimization and various stability and performance constraints along with the constraints on the closed-loop eigenvalues are imposed on the structure. Weighting method, goal programming technique and modified game theory are used as multiobjective optimization techniques to collapse the three objective functions into one single objective function. A substructural control technique is employed for the structural control design in order to reduce the computational cost of the optimization procedure. The proposed multiobjective control optimization scheme produces optimum structure/control design and because of its numerical efficiency, it can be applied to large flexible structures.
