Topology optimization of Piezoelectric Macro Fiber Composite Patches on Composite Plates for active vibration control

This paper presents a topology optimization methodology of piezoelectric actuators in laminated composite structures. The Linear Quadratic Regulator (LQR) optimal control technique is used. The topology optimization is formulated to find the optimum localization of the Macro Fiber Composite (MFC), through of the maximization of the controllability index. Actuator location optimization results show that the technique implemented improves the structural vibration damping.
