Abstract: “The design method capable of simultaneously considering the factors related to control system and structural system, and satisfying the multiple design objects as well is proposed. This problem has usually trade-off factors and complex design situation. One of set-based design methods, preference set-based design (PSD), is applied to the simultaneous design problem of the arm structure with stepped shape under rotational motion. In PSD method, the design variables and performance variables are represented by interval set with designer’s preference function and, solution sets are obtained considering high robustness and satisfaction of required performances. Simulation using PID controller in control engineering is performed. As a result, by using PSD method, each interval set of multiple design parameters related to the shape of the arm and the control system is obtained simultaneously satisfying multiple required performances appropriately.”
