This paper presents topology/shape and control system optimization to achieve the required vibration control performance. A smart structure is composed of the piezoelectric film sensors and actuators. The structure is modeled by finite element analysis, and modal analysis is applied to the model obtained by the finite element analysis to reduce the order. For topology/shape optimization, the density of each finite element is adopted as design variable. In this paper, we show that the optimal distribution of the density and the optimal controller can be simultaneously designed by the presented approach with the two-step algorithm. The effectiveness of the proposed method is verified by some simulation results.
