Medientyp: E-Artikel Titel: Optimal control for indoor overhead crane systems with predefined course of crab Beteiligte: Blume, Bodo; Büskens, Christof Erschienen: Wiley, 2008 Erschienen in: PAMM Sprache: Englisch DOI: 10.1002/pamm.200810107 ISSN: 1617-7061 Schlagwörter: General Medicine Entstehung: Anmerkungen: Beschreibung: <jats:title>Abstract</jats:title><jats:p> Most papers on optimal control of 3D overhead cranes focus on systems without constraints for the course of the crab (for example [1], [3]). Based on a general 3D model a minimal model with 2 degrees of freedom is developed. Starting from a given initial state the optimal control to reach a given final state is calculated for some predefined courses of the crab. For different turning angles and speeds of the crab an arc of a sine, parabola, circular and an arc of two symmetric clothoid segments have been investigated. Calculations for different values of the mass of the load, turning angles and speed of the crab are presented. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)</jats:p> Zugangsstatus: Freier Zugang
