Van der Steen, P.M.H. (author)During rough wave climates, vessel motions prevent people to be transferred safely form and to an offshore structure. The Ampelmann system is a ship-based, self stabilizing platform that actively compensates all vessel motions to make acces to offshore structures safe, easy and fast. The Ampelmann system uses a Steward platform to compensate...master thesis 2016

Dimitrova, I.D. (author)The natural frequency of wind turbine towers can be more than 10% off from the designed frequency. This frequency is important for control because it sets bandwidth limits to some of the control loops. Improving the model will result in better control and load reduction that will in turn contribute to the decrease of the cost of wind energy. The...master thesis 2016

Molenaar, J.C.R. (author)In research, training and entertainment industries, simulators are used to replicate human perception of vehicle motion in a safe and customizable environment. The perception of self- motion of the driver inside the simulator is improved by the presence of motion cues generated by a motion system. However, direct feedthrough of these vehicle...master thesis 2015

Zhu, J. (author)The thesis contributes to the pre-collision strategies of robot manipulators by proposing a real-time implementable collision avoidance scheme. The collision is avoided by a braking controller that is activated by a braking trajectory predictor. The predictor provides distances of the end-effector to the object/human in the environment and...master thesis 2015

Gonzalez Ramirez, R.I. (author)The use of telepresence becomes an alternative in scenarios such as deep sea maneuvers, inspection and maintenance in hazardous environments or aerial surveillance tasks, amongst some other robotic tasks. In some of these cases, human deployment might be dangerous, expensive and even not possible yet. Because of the wide variety and increasing...master thesis 2015

Pane, Y.P. (author)For a robot manipulator, an accurate reference tracking capability is one of the most important performance factor. This is especially the case for a robot which is deployed for an industrial use such as welding and laser cutting. Recently, an emerging application of 3D printing also attracts researchers to use robotic manipulators in hope of...master thesis 2015

Nugroho, H. (author)Optical beamforming networks (OBFNs), which consist of many small and flat antennas, called phased array antennas (PAAs), can be tuned such that the signal beam from the airplanes can be steered towards a satellite. This was proposed as a alternative to the mechanically steered antenna, which has many disadvantages. The problem of tuning a large...master thesis 2015

Bhattacharjee, A. (author)The dynamics of many physical processes can be described by port-Hamiltonian (PH) models where the importance of the energy function can be seen. In Control by Interconnection (CbI), the controller is another PH system that is connected to the plant through a power preserving interconnection to add up the energy functions. However, a major issue...master thesis 2015
