Liu, Y. (author), Pamososuryo, A.K. (author), Ferrari, Riccardo M.G. (author), van Wingerden, J.W. (author)The Immersion and Invariance (II) wind speed estimator is a powerful and widely-used technique to estimate the rotor effective wind speed on horizontal axis wind turbines. Anyway, its global convergence proof is rather cumbersome, which hinders the extension of the method and proof to time-delayed and/or uncertain systems. In this letter, we...journal article 2022

Tajdari, F. (author)Aiming at a more efficient and accurate performance of parallel manipulators in the existence of complex kinematics and dynamics, a robust generalizable methodology is proposed here for an integrated 6-DOF Stewart platform with rotary time-delayed actuators torque control. The suggested method employs a time-delay linear–quadratic integral...journal article 2022

Dun, H. (author)Accurate position solutions are in high demand for many emerging applications. Global navigation satellite systems (GNSS), however, may not meet the required positioning performance, especially in urban environments, due to multipath and weak received power of the GNSS signal that can be easily blocked by surrounding objects. To achieve a high...doctoral thesis 2021

Jansen, Jesse (author)Conversational agents are being used more often. Many conversational agents have been designed to make them more humanlike to increase the engagement of the user. This research is looking into a couple of aspects of anthropomorphism to determine whether these aspects improve the engagement of the users. These aspects are typos with time delay...bachelor thesis 2021

Levenbach, Robert (author)In this research, Dutch phoneme recognition (PR) is researched and improved. The last research on Dutch PR dates back to 1995. This research presents Dutch PR in modern daylight by researching state-of-the-art techniques found in research on other languages and implementing them on Dutch PR. The goal of this research is to find the current best...master thesis 2021

Roy, S. (author), Lee, Jinoh (author), Baldi, S. (author)This brief proposes a new adaptive-robust formulation for time-delay control (TDC) under a less-restrictive stability condition. TDC relies on estimating the unknown system dynamics via the artificial introduction of a time delay, often referred to as time-delay estimation (TDE). In conventional TDC, the estimation error, called TDE error, is...journal article 2021

van den Berg, Boudewijn (author), Manoochehri, M. (author), Kasting, Mindy (author), Schouten, A.C. (author), van der Helm, F.C.T. (author), Buitenweg, Jan R. (author)A sustained sensory stimulus with a periodic variation of intensity creates an electrophysiological brain response at associated frequencies, referred to as the steady-state evoked potential (SSEP). The SSEPs elicited by the periodic stimulation of nociceptors in the skin may represent activity of a brain network that is primarily involved in...journal article 2021

Dun, H. (author), Tiberius, C.C.J.M. (author), Diouf, C.E.V. (author), Janssen, G.J.M. (author)This paper presents a methodology to design a sparse multiband ranging signal with a large virtual bandwidth, from which time delay and carrier phase are estimated by a low complexity multivariate maximum likelihood (ML) method. In the estimation model for a multipath channel, not all reflected paths are considered, and time delay and carrier...journal article 2021

Roy, Spandan (author), Baldi, S. (author), Li, Peng (author), Narayanan, Viswa (author)Artificial-delay control is a method in which state and input measurements collected at an immediate past time instant (i.e. artificially delayed) are used to compensate the uncertain dynamics affecting the system at the current time. This work formulates an artificial-delay control method with adaptive gains in the presence of nonlinear ...journal article 2021

de Groot, O.M. (author), Keviczky, T. (author)In this work we consider the problem of cooperative end-effector control between heterogeneous fully actuated agents when varying-time delays and/or packet loss are present. We couple agents via outputs encoded with task-space coordinates and velocities that are transformed into wave-variables to overcome the destabilising effects of the...journal article 2021

Kuipers, Sterre (author)Part of the goal of Europe’s Strategy Vision Zero is to eliminate all severe cycling accidents in Europe by 2030. The majority of cycling accidents are single vehicle accidents; this term indicates the absence of collisions with other road participants and implies a fall of the cyclist. Research has shown that mainly elderly cyclists are victim...master thesis 2020

Golestani, Mehdi (author), Mobayen, Saleh (author), Hassan HosseinNia, S. (author), Shamaghdari, Saeed (author)This article proposes a new nonlinear state-feedback stability controller utilizing linear matrix inequality (LMI) for time-delay nonlinear systems in the presence of Lipschitz nonlinearities and subject to parametric uncertainties. Following the Lyapunov–Krasovskii stabilization scheme, the asymptotic stability criterion resulted in the LMI...journal article 2020

Dun, H. (author), Tiberius, C.C.J.M. (author), Diouf, C.E.V. (author), Janssen, G.J.M. (author)Time-based ranging accuracy is inversely proportional to the signal bandwidth. A larger the signal bandwidth leads to a higher accuracy of time delay estimation, but more complex hardware is needed. Alternatively, we explore the idea of using multiple narrow signal bands (e.g., 10 MHz of each) to create a large virtual signal bandwidth, which...conference paper 2020

REDDY, Sahana (author)Most of the large infrastructure projects (LIPs) are characterized with significant time delays and cost overruns. In order to be able to deploy the LIPs more effectively, make optimal use of the resources and investments and timely deliver the projects NETLIPSE was set up. NETLIPSE developed a project assessment tool called the Infrastructure...master thesis 2019

Fu, W. (author), van Paassen, M.M. (author), Abbink, D.A. (author), Mulder, Max (author)Time delays in haptic teleoperation affect the ability of human operators to assess mechanical properties (damping, mass, and stiffness) of the remote environment. To address this, we propose a unified framework for human haptic perception of the mechanical properties of environments with delayed force feedback. In a first experiment, we...journal article 2019

Putter, Yvo (author)In The Netherlands, the current heat energy system accounts for 44% of the primary energy usage and relies almost entirely on fossil fuels such as natural gas. To meet the Paris Climate Agreement goals, 4th Generation District Heating (4GDH) networks are expected as sustainable heat energy system solution. The concept relies on optimally...master thesis 2018

Yuan, S. (author)As a special class of hybrid systems, switched systems have attracted a lot of attention in the last decade due to theoretical and practical interests. When controlling switched systems, a ubiquitous problem is the presence of large parametric uncertainties and external disturbances. However, the state of the art on adaptive and robust control...doctoral thesis 2018

Su, Libo (author), Wei, Yanling (author), Michiels, Wim (author), Steur, E. (author), Nijmeijer, Henk (author)Networks of interconnected dynamical systems may exhibit a so-called partial synchronization phenomenon, which refers to synchronous behaviors of some but not all of the systems. The patterns of partial synchronization are often characterized by partial synchronization manifolds, which are linear invariant subspace of the state space of the...journal article 2018

Pinto Rebelo, J.L. (author)Robots are particularly well suited for executing tasks that take place in locations which are too dangerous or inaccessible to human operators. For robot manipulators to execute complex activities in unknown, unstructured environments, despite the recent increases in computation power, human input is still required for task planning and...doctoral thesis 2015
