Norrish, John (author), Polden, Joseph (author), Richardson, I.M. (author)Additive manufacturing (AM) is now recognised as a viable alternative to processes such as casting, forging, and subtractive technologies such as machining. Wire arc additive manufacturing (WAAM) has emerged as a cost-effective AM approach for component fabrication and a considerable body of literature on the subject has become available over...review 2021

van Woerkom, P.T.L.M. (author)The document contains a general theory towards the observation and optimal control of disturbed, target following aerospace systems. Disturbed, target following aerospace systems eire defined as aerospace systems that are designed to track a moving target system, while they are subjected to external, time-varying disturbances. The first five...report 1976

van Woerkom, P.T.L.M. (author), Guelman, M. (author)Four well-known formalisms for mathematical modelling of the dynamics of a spacecraft/manipulator system are derived from the unifying d'Alembert principle. The Newton-Euler formalism is discussed in more detail, as it allows efficient numerical simulation. An algorithm is defined for the control of the manipulator end-effector motion in...report 1987

Prins, J.J.M. (author), Dieleman, P. (author), de Jong, H. (author)The Hermes manipulation system (HERA) is a sophisticated space manipulator system, which has to perform tasks ranging from berthing to tool operation in various operational modes from fully automatic to purely manual. The HERA system main contractor is Fokker Space & Systems B.V. (FSS). Development and qualification of such a space-based...report 1989

van den Assem, D. (author), Bunk, P.B. (author)Preliminary experiments have been performed with a laboratory model of an electro-osmotic heat pipe filled with ethanol. With dismounted electro-osmotic pump, the heat transport through the pipe and the temperature distribution along the pipe wall have been measured. The measurements have been performed as a function of the temperature...report 1983

Bos, J.F.T. (author), Faasse, P.R. (author)The High Speed wind Tunnel (HST) of the National Aerospace Laboratory NLR is one of the major transonic windtunnels and is used for aerodynamic research on scale models. The measurements require the control of the Mach number. Two kinds of controller tasks can be distinguished: keeping the Mach number constant, and realizing a different Mach...report 1992

Voglitsis, D. (author)The utilization of IPT technology in electric vehicles (EVs) charging applications and in the microgrid restoration/islanding mode, has the potential to bring about a change in how EVs are perceived today. Firstly in consumer level, by making the charging process more convenient, safe and user-friendly, by removing the messy cords , and secondly...master thesis 2014

Vicente Melo E Carvalho Marques, Mariana (author)L1 adaptive control is a relatively new technique that attempts to tackle the robustness shortcoming of the MRAC controller by applying a low pass filter to the control input. It can be used as an augmentation loop using baseline controllers such as backstepping or PID. This controller has been implemented as an augmentation loop with both these...master thesis 2017

Fernandez Barrio, Jorge (author)A proportionate controller is investigated experimentally for unsteady load alleviation purposes on a 2D wing model with a trailing edge flap. This study is supposed to be a simplified version of a Smart Rotor, a mechanism which deals with the reduction of unsteady loads acting on a wind turbine and aims to understand the behavior of this type...master thesis 2020

van der Spaa, Linda (author)Current robots consume a lot of energy. The work required for a task is generally just a tiny fraction of the total energy consumed. Most energy wastefully dissipated. Design of the 2 degree of freedom (DoF) Plugless Robot Arm shows that clever design can reduce these energy losses to a tiny remaining fraction. The Plugless Arm is designed to...master thesis 2017
