Paper Abstract

A design technique is presented to improve the overall performance of a structural system by simultaneously optimizing the design of the structure and an associated controller. This procedure requires the minimization of a single objective function, subject to dimensional or mass constraints. This is done by including the control and disturbance forces in the equations of motion for the structure and using the eigenfunctions of a uniform structural design as a basis for the eigenfunctions of the optimally designed, nonuniform structure. The results of the concurrent optimization of an Euler-Bernoulli beam and H2 controller are presented. More complicated structures/controllers can be designed using this technique, provided the structure can be modeled as a linear time-invariant plant and the controller synthesis technique involves a single cost functional.
