Abstract :
Integrated design for actively controlled systems is considered in this paper. The improvement can be obtained in the overall performance of an actively controlled structure by simultaneously optimizing the structural and control design. The purpose of this paper is to analyze the existence condition of optimal solutions for structural parameters. A quadratic index is used to evaluate the system performance and its sensitivities to structural parameter changes are derived to study the conditions for the optimal solution. The effect of an active control on the existence condition is discussed
