Florea, Radu (author)In this MSc. thesis, state estimation for a nanosatellite-class reaction wheel has been investigated. Two LPV observers, using different sensor information, have been synthesized. The performance of the designed observers has been evaluated using a detailed simulation of the reaction wheel (including disturbances that occur during the reaction...master thesis 2018

Suresh Kumar, Nivas Kumar (author)In research, the overall power production in a wind farm is typically increased by employing model-based wind farm control. A controller, in an open-loop setting, operates based on the velocity of the wind flow, predicted by a wind farm model. For a controller to achieve the desired level of power production, a wind farm model has to be accurate...master thesis 2018

van Erp, P.B.C. (author), Knoop, V.L. (author), Hoogendoorn, S.P. (author)This article presents a procedure to estimate the macroscopic traffic state in a pre-defined space-time mesh using relative flow data collected by stationary and moving observers. The procedure consist of two consecutive and independent processes: (1) estimate point observations of the cumulative vehicle number in space-time, i.e., N(x, t),...journal article 2018

Sun, Junzi (author), Blom, H.A.P. (author), Ellerbroek, Joost (author), Hoekstra, J.M. (author)This paper focuses on estimating aircraft mass and thrust setting using a recursive Bayesian method called particle filtering. The method is based on a nonlinear state-space system derived from aircraft point-mass performance models. Using solely ADS-B and Mode-S data, flight states such as position, velocity, and wind speed are collected and...conference paper 2018

Picallocruz, M. (author), Anta, Adolfo (author), De Schutter, B.H.K. (author), Panosyan, Ara (author)In this paper we consider the problem of State Estimation (SE) in large-scale, 3-phase coupled, unbalanced distribution systems. More specifically, we address the problem of including mixed real-time measurements, synchronized and unsynchronized, from phasor measurement units and smart meters, into existing SE solutions. We propose a...conference paper 2018

van der Arend, Marco (author)One of the phases of the installation of Offshore Wind Turbines is the installation of the foundation for the turbine. Herein, a monopile is one of the most frequently used foundation-types. This monopile is a high steel cylinder, over 60 meters high, which supports the wind turbine to the seabed. Currently, monopiles are lifted with large boom...master thesis 2017

Duret, Aurélien (author), Yuan, Y. (author)The paper proposes a model-based framework for estimating traffic states from Eulerian (loop) and/or Lagrangian (probe) data. Lagrangian-Space formulation of the LWR model adopted as the underlying traffic model provides suitable properties for receiving both Eulerian and Lagrangian external information. Three independent methods are proposed...journal article 2017

Tatsis, K. (author), Chatzi, Efi (author), Thons, S. (author), Lourens, E. (author)The evaluation of fatigue damage accumulation on wind turbine support structures under operational conditions is heavily influenced by a number of uncertainties. These uncertainties may, firstly, be attributed to the highly variable and complex environmental loads, and secondly, to the unavoidable modelling errors which mainly originate from the...conference paper 2017

Lu, P. (author), van Kampen, E. (author), de Visser, C.C. (author), Chu, Q. P. (author)The design of unknown-input decoupled observers and lters requires the assumption of an existence condition in the literature.This paper addresses an unknown input ltering problem where the existence condition is not satised. Instead of designing a traditional unknown input decoupled lter, a Double-Model Adaptive Estimation approach is extended...journal article 2016

Paiman (student), Charlotte (author), Lemus Perez, D.S. (author), Short Sotero, D.M. (author), Vallery, H. (author)The occurrence of falls is an urgent challenge in our aging society. For wearable devices that actively prevent falls or mitigate their consequences, a critical prerequisite is knowledge on the user’s current state of balance. To keep such wearable systems practical and to achieve high acceptance, only very limited sensor instrumentation is...journal article 2016
