Abstract

A multiobjective optimization procedure is developed to address the combined problems of the synthesis of structures/controls and the actuator-location problem for the design of intelligent structures. Continuous and discrete variables are treated equally in the formulation. Multiple and conflicting design objectives such as vibration reduction, dissipated energy, power and a performance index are included by utilizing an efficient multiobjective optimization formulation. Piezoelectric materials are used as actuators in the control system. A simulated annealing algorithm is used for optimization and an approximation technique is used to reduce computational effort. A numerical example using a cantilever box beam demonstrates the utility of the optimization procedure when compared with a previous nonlinear programming technique.
