Abstract

A methodology is proposed for designing a structure and robust control for optimum performance. The problem is formulated as a nonlinear mathematical optimization problem with structural weight as the objective function and constraints within the realm of structural and control design requirements. The control approach selected for this investigation is based on multi-input multi-output H₂ - H_(infinity ) theory which can tolerate structured and unstructured uncertainties. The constraints were imposed on the structural frequencies and gain separation between open-loop and closed-loop systems. The application of the design methodology is illustrated on a wing box idealized with bar elements and composite box-beam.
