The simultaneous structure/control design synthesis of a wing is considered with an active control system called the Gust Load Alleviation (GLA) system. A fuzzy decision-making method is applied to the allowable maximum level of the gust-induced stress when the control system fails. A simple wind tunnel model excited by a random gust is studied. The thickness of a FEM beam element modeling the wing spar and the feedback control gain are optimized to maximize the fuzzy decision with the prioritized design requirements, e. g., the control system's stability characteristics, and the standard deviation of the gust-induced stress and control surface deflection angle with the control system on. The sequential linear approximation method is proposed to obtain the optimum solutions for nonlinear multigoal problems with fuzzy goals.
