Abstract:

In this paper the authors have investigated the effect of passive damping on the optimum structural design with active controls. The minimum weight design is obtained by imposing the constraints on the active damping parameter and the imaginary part of the closed-loop eigenvalues of the closed-loop system for linear quadratic regulator. The integrated structural and control optimization problem is solved by using NEWSUMT-A program which is based on extended interior penalty function formulation. The ACOSS-FOUR model is selected for the study.
