Optimal Direct Velocity Feedback

摘要: We present a novel approach to the problem of Direct Velocity Feedback (DVF) optimization vibrational structures, which treats simultaneously small as well large gains. For that purpose, we use two different approaches. The first one is based on gains using Lyapunov equation. In scope this new formula for optimal gain and relative error modal approximation. addition, solution corresponding equation case with multiple undamped eigenfrequencies, generalization existing formulae. second studies behavior eigenvalues quadratic eigenvalue problem. Since leads parametric consider separately. gains, are connected damping approximation, standard Gerschgorin discs. allows us approximate all very accurately efficiently.
