Meijers, P. (author), van Woerkom, P.T.L.M. (author)Met de overgang van de Polytechnische School naar de Technische Hoogeschool in 1905 werd ook binnen de destijdse Afdeling der Werktuigbouwkunde en Scheepsbouwkunde de behoefte en de noodzaak gevoeld om haar onderwijs en onderzoek naar een hoger wetenschappelijk niveau te tillen. Nieuwe hoogleraren werden benoemd, een enkeling zelfs nog...book chapter 2017

van Woerkom, P.T.L.M. (author)In het jaar 1816 formuleerde de Franse wiskundige J.D. Gergonne het volgende probleem: beschouw een familie van oppervlakken welke aan boven- en onderzijde zijn opgespannen door twee diagonalen van een kubus, en waarvan de zijranden op zijvlakken van die kubus liggen. Welke vorm heeft de minimale oppervlakte? Dit probleem werd in 1865 door H.A....book chapter 2017

Van Woerkom, P.T.L.M. (author)Op 8 september 2004 is het zestig jaar geleden dat de eerste Duitse V2-raketten uit de omgeving van de Haagse Konijnenlaan werden afgevuurd op Londen. Dat was het begin van een luchtoorlog die vanaf de herfst van 1944 zeven maanden zou duren en die zijn weerga in de geschiedenis nauwelijks kent. Meer dan duizend V2’s werden uiteindelijk vanaf...journal article 2004

Van Woerkom, P.T.L.M. (author)Much has been written about the German Vengeance weapons V-1 and V-2, in particular about the design and the designers of the V-2 rocket, which was preferably seen as the first engineering tool for reaching space. But they were meant to be weapons of war for massive destruction of civilians and property. Before the V-weapon offensive started,...conference paper 2003

Chu, Q.P. (author), Zwartbol, T. (author), van Woerkom, P.T.L.M. (author)The objective of the present paper is to give an overview of spacecraft attitude determination with GPS. GPS receivers with single or multiple antennas nowadays are low-cost sensors that constitute a valuable complement to existing sensor suites. GPS has been widely used for positioning and vehicle navigation. However, using GPS as an attitude...report 1995

Pronk, Z. (author), van Woerkom, P.T.L.M. (author)Computer simulation and testing of zero-gravity operations in support of development of space structures becomes more and more standard. Yet, the need for hardware simulation and test facilities representing zero-gravity conditions remains necessary, because of the strong requirements for verification and validation of system responses and model...report 1995

Misra, A.K. (author), van Woerkom, P.T.L.M. (author)Large robotic manipulators are to play a key role in assembly, maintenance, and servicing of future complex inorbit infrastructures. The first generation space manipulator is the Canadian Remote Manipulator System (RMS), in orbit since 1981. A second generation of large space manipulators is presently under development, for use on the...report 1995

van Woerkom, P.T.L.M. (author), de Boer, A. (author), Ellenbroek, M.H.M. (author), Wijker, J.J. (author)A brief description is given of the European Robot Arm (ERA), and its intended application to assembly, maintenance, and servicing of the Russian segment of the International Space Station Alpha. The need for manipulator simulation is recalled, and ERA simulator development is outlined. System characteristics that must be modelled for...report 1994

van Woerkom, P.T.L.M. (author), Guelman, M. (author), Ehrenwald, L. (author)The paper focuses on Indirect adaptive control of space robot manipulators when maneuvering payloads with Imperfectly known mechanical parameters. The objective Is to estimate system mechanical parameters during the maneuver Itself. The system bodies are rigid, and are concatenated by ideal, rotational Joints. Existing adaptive control laws are...report 1993

van Woerkom, P.T.L.M. (author)The paper considers the dynamics of flexible space manipulators carrying out relatively fast maneuvers. In the past, computer simulations of the dynamics of flexible space manipulators executing large movements sometimes lacked in accuracy, especially during fast maneuvers. This deficiency can be attributed to the neglect of second-order terms...report 1991

van Woerkom, P.T.L.M. (author)The report contains the development of the dynamics equations of a spacecraftmanipulator system with chain topology. The spacecraft may be flexible. The attached manipulator consists of an arbitrary number of links, connected by single degree-of-freedom rotational joints. None, any, or all of the links may be flexible. A rigid or flexible...report 1990
