ENHANCED ROBUSTNESS IN INTEGRATED STRUCTURAL CONTROL-SYSTEMS DESIGN

This paper addresses maximizing the robustness of an integrated structural/control system for increasing the stability margin under parametric uncertainties. The robustness limit is defined for a linear time-invariant system consisting of structured perturbations. The optimization problem has considered the closed-loop eigenvalues, damping parameter, and robustness as design constraints. Effects of increasing the stability robustness of a closed-loop system are demonstrated on two structural optimization examples.
