Titre : Command shaping for flexible systems subject to constant acceleration limits Type de document : texte imprimé Auteurs : Jon Danielson, Auteur ; Lawrence, Jason, Auteur ; William Singhose, Auteur Année de publication : 2008 Article en page(s) : 8 p. Note générale : dynamic systems Langues : Anglais (eng) Mots-clés : cranes  vibration  flexible systems  impulse (physics) Résumé : Input shaping is an effective means of eliminating vibration in many types of flexible systems. This paper discusses how input shaper performance is affected by a fixed acceleration limit. This type of limit is a common occurrence in many mechanical drive systems because it corresponds to a constant force or torque input. It is shown that some input shapers are not affected by an acceleration limit under certain conditions. A test criterion is developed to determine what types of input shapers are negatively affected, and a method is proposed to compensate for the detrimental effects of the constant acceleration limit. Experimental results from an industrial crane support the main theoretical results.
