Abstract: The structure and vibration control system of smart laminated composites consisting of graphite-epoxy composites and piezoelectric actuators are designed for optimum vibration suppression. The placement of piezoelectric actuators, the lay-up configurations of laminated composite plates, and the H2 control system are employed as design variables and they are optimized simultaneously by a simple genetic algorithm (SGA). To reduce complexity, only pre-selected families of lay-up configurations are considered. An objective function is the H2 performance with respect to the controlled response for vibration suppression. A multidisciplinary design optimization is performed with the above three design variables and then the output feedback system is reconstructed with a dynamic compensator based on a linear matrix inequality (LMI) approach. The validity of the modeling and calculation technique is confirmed experimentally. Optimization results show that optimized smart composites with the present approach successfully realize vibration suppression and it is confirmed that the proposed multidisciplinary design optimization technique enhances the vibration suppression of smart composites.
