Rechnergestützter Entwurf -CAD- und Implementierung schneller und robuster Antriebsregelungen für Industrieroboter

Aus der Literatur sind zahlreiche anspruchsvolle Regelungsalgorithmen für Industrieroboter bekannt, die unter akademischen Laborbedingungen ausgezeichnete Ergebnisse liefern. Die Mehrheit der marktüblichen Robotersteuerungen bevorzugen jedoch eher einfache, konservative Regelungskonzepte. Die Hauptgründe für die Nichtakzeptanz sind die hohen Inbetriebnahmekosten, die aufwendigen Hardwareanforderungen sowie die unbefriedigende Robustheit gegenüber Schwankungen oder Unsicherheiten der Modellparameter. Für zukünftige Anwendungen in CIM-Systemen werden jedoch in zunehmendem Maße eine bessere Regelgüte, hohe Robustheit in rauher Industrieumgebung, einfachere Entwurf- und Inbetriebnahmemethoden mit PC-Unterstützung sowie Implementierbarkeit auf preisgünstiger gängiger Mikrorechnerhardware gefordert. Die in diesem Beitrag vorgestellte prädiktive PFC-Regelung stellt ein sinnvolles Alternativkonzept dar, das den genannten Anforderungen optimal gerecht werden kann. Das PFC-Regelungskonzept wurde für einen konventionellen Industrieroboter des Typs Kuka 160 realisiert. Anhand verschiedener experimenteller Untersuchungen sowie eines Benchmarktestes wird die Überlegenheit des PFC-Regelungskonzepts gegenüber der konventionellen PI-Regelung nachgewiesen. (IITB

Resources for teaching technical services in a rapidly changing global environment

The global information context is changing rapidly, and resources to support instruction relating to the evolving standards and practices in technical services are in high demand. What do we need and how robust are the resources that are available? What can and should Technical Services educators do to best prepare information professionals in the face of this evolving context, world-wide? This panel will address these and other questions related to materials used for teaching technical services courses, while also considering the audience for the materials, from three complementary perspectives. Drawing from an analysis of existing courses offered by Master’s programs in LIS, competencies developed by professional organizations, job descriptions, relevant literature, and feedback from students and instructors, the first panel presentation will take a look at the current state of information organization education, including resources used, topics covered, and training gaps. The second panel presentation will reflect on technical services instruction for school and public librarians in particular, exploring the relationship between theory and practice for cataloging instruction. The third panel presentation will address the topic of providing Open Educational Resources (OERs), highlighting the panelist’s experiences on a university’s OER task force and as a grant recipient. The results shared will consist of a perspective of graduate LIS faculty on institutional OER initiatives, which are usually focused on undergraduate education, particularly in the sciences, as well as a view of creating OERs for a graduate level LIS course on a technical services topic The session will be co-moderated by the SIG sponsors. The moderators will introduce the topic, providing initial background and insight on the problem of the rapidly-changing field of technical services and the educational needs. Time at the end will be reserved for interaction with the audience
