Abstract
This paper considers the combined structural and control optimization problem for flexible systems. The sum of structural weight and controlled system energy terms is minimized simultaneously in structural and control parameters using gradient searches. The purpose of control is to effectively suppress structural vibrations due to initial excitations. Starting with a baseline structural design, the objective of the combined structural/control optimization is to produce a lighter weight structure with, when excited, reduced vibrational and control energy content. Control weighing matrix selection and dependence of optimal designs upon initial conditions are discussed. The ideas presented are illustrated through numerical simulations using a 10-bar cantilevered truss.
