Input shaping control of double-pendulum bridge crane oscillations / William Singhose in Transactions of the ASME . Journal of dynamic systems, measurement, and control, Vol. 130 N° 3 (Mai/Juin 2008) 

Public ISBD [article]  in Transactions of the ASME . Journal of dynamic systems, measurement, and control > Vol. 130 N° 3 (Mai/Juin 2008) . - 07 p. Titre : Input shaping control of double-pendulum bridge crane oscillations Type de document : texte imprimé Auteurs : William Singhose, Auteur ; Michael Kenison, Auteur ; Dooroo Kim, Auteur Année de publication : 2010 Article en page(s) : 07 p. Note générale : dynamic systems Langues : Anglais (eng) Mots-clés : crane  payloads;  oscillation;  input  shaping  controller Résumé : Large amplitude oscillation of crane payloads is detrimental to safe and efficient operation. Under certain conditions, the problem is compounded when the payload creates a double-pendulum effect. Most crane control research to date has focused on single-pendulum dynamics. Several researchers have shown that single-mode oscillations can be greatly reduced by properly shaping the inputs to the crane motors. This paper builds on those previous developments to create a method for suppressing double-pendulum payload oscillations. The input shaping controller is designed to have robustness to changes in the two operating frequencies. Experiments performed on a portable bridge crane are used to verify the effectiveness of this method and the robustness of the input shaper.
