Titre : Minimax state/residual-energy constrained shapers for flexible structures : linear programming approach Type de document : texte imprimé Auteurs : Matthew Vossler, Auteur ; Singh, Tarunraj, Auteur Année de publication : 2010 Article en page(s) : 08 p. Note générale : Systèmes dynamiques Langues : Anglais (eng) Mots-clés : Control  system  synthesis  Flexible  structures  Linear  programming  Minimax  techniques  Robust  control  Vibration  control Index. décimale : 629.8 Résumé : The focus of this paper is on the design of shaped profiles subject to transient state constraints and terminal energy limits. The issue of robustness to modeling errors is addressed by formulating a minimax optimization problem in a linear programming framework, permitting the generation of near-globally optimal shaped profiles. To illustrate the proposed technique, a deflection-limited/residual energy constrained, controller design for flexible structures undergoing rest-to-rest maneuvers will be presented. Techniques for improving robustness by the addition of state sensitivity equations, which increases the robustness in the vicinity of the nominal model, are explored. Results for the benchmark oscillator illustrate the benefit of the proposed approach over traditional designs.
