Arkesteijn, L. (author), Blom, A. (author), Labeur, R.J. (author)Recent analysis of equilibrium and quasi-equilibrium channel geometry in engineered (fixed-width) rivers has successfully shown that two temporal scales can be distinguished, with quasi-static (long-term) and dynamic (short-term) components. This distinction is based on the fact that channel slope cannot keep pace with short-term fluctuations...journal article 2021

Trumic, Maja (author), Della Santina, C. (author), Jovanovic, Kosta (author), Fagiolini, Adriano (author)Despite having proven successful in generating precise motions under dynamic conditions in highly deformable soft-bodied robots, model based techniques are also prone to robustness issues connected to the intrinsic uncertain nature of the dynamics of these systems. This letter aims at tackling this challenge, by extending the augmented rigid...journal article 2021

van der El, Kasper (author), Pool, D.M. (author), van Paassen, M.M. (author), Mulder, Max (author)The 1960s crossover model is widely applied to quantitatively predict a human controller's (HC's) manual control behavior. Unfortunately, the theory captures only compensatory tracking behavior and, as such, a limited range of real-world manual control tasks. This article finalizes recent advances in manual control theory toward more general...journal article 2020

Khodadadian, F. (author)Photocatalysis involves the absorption of photons by a semiconductor to enhance chemical reactions. Examples of important applications include the degradation of hazardous chemicals, reduction of carbon dioxide to valuable chemicals and (partial) oxidation of hydrocarbons. Despite many successful demonstrations of this technology at lab-scale,...doctoral thesis 2019

Willems, M. (author), Pool, D.M. (author), van der El, Kasper (author), Damveld, H.J. (author), van Paassen, M.M. (author), Mulder, Max (author)Human modelling approaches are typically limited to feedback-only, compensatory tracking tasks. Advances in system identification techniques allow us to consider more realistic tasks that involve feedforward and even precognitive control. In this paper we study the human development of a feedforward control response while learning to...journal article 2019

Purgat, P. (author), van der Blij, N.H. (author), Qin, Z. (author), Bauer, P. (author)Scalable and robust low-voltage direct current (LVdc) distribution networks require solutions, allowing flexible power flow control and reliable short-circuit protection. In this paper, the continuous full-order large-and small-signal models of a partially rated power flow control converter (PFCC) are derived utilizing the generalized...journal article 2019

Barendswaard, S. (author), Pool, D.M. (author), van Paassen, M.M. (author), Mulder, Max (author)Vehicle control tasks require simultaneous control of multiple degrees-of-freedom. Most multi-axis human-control modeling is limited to the modeling of multiple fully independent single axes. This paper contributes to the understanding of multi-axis control behavior and draws a more realistic and complete picture of dual-axis manual control....journal article 2019

Kajak, K. M. (author), Karasek, M. (author), Chu, Q. P. (author), de Croon, G.C.H.E. (author)Recently, several insect- and hummingbird-inspired tailless flapping wing robots have been introduced. However, their flight dynamics, which are likely to be similar to that of their biological counterparts, remain yet to be fully understood. We propose a minimal dynamic model that is not only validated with experimental data, but also able...journal article 2019

de Athayde Costa e Silva, M. (author), Silvestrini, Stefano (author), Cordeiro Guerrieri, D. (author), Cervone, A. (author), Gill, E.K.A. (author)This brief presents a comprehensive approach for the modeling of micropropulsion systems based on the vaporization of a liquid. The model combines the analytical and empirical relations derived from extensive experimental analysis and fundamental physical laws. This allows modeling of key parameters, such as mass flow rate, for the entire...journal article 2018

van der El, Kasper (author), Padmos, S. (author), Pool, D.M. (author), van Paassen, M.M. (author), Mulder, Max (author)In manual control tasks, preview of the target trajectory ahead is often limited by poor lighting, objects, or display edges. This paper investigates the effects of limited preview, or preview time, in manual tracking tasks with single- and double-integrator controlled element dynamics. A quasi-linear human controller model is used to predict...journal article 2018

Smit, B. (author)A new type of polymeric artificial muscle was recently discovered. This muscle is based on twisted and coiled polymer fiber and is actuated thermally. It has interesting properties, such as low costs and high work densities. Based on fabrication methods, two variations can be considered. The autocoiled variation has a larger load capacity and...master thesis 2016

Drop, F.M. (author), Pool, D.M. (author), Mulder, Max (author), Bülthoff, Heinrich H. (author)The human controller (HC) can greatly improve target-tracking performance by utilizing a feedforward operation on the target signal, in addition to a feedback response. System identification methods are used to determine the correct HC model structure: purely feedback or a combined feedforward/feedback model. In this paper, we investigate three...journal article 2016

Drop, F.M. (author), Mulder, Max (author), Bülthoff, Heinrich H. (author), de Vries, R. (author)In the manual control of a dynamic system, the human controller (HC) is often required to follow a visible and predictable reference path. Using the predictable aspect of a reference signal, through applying feedforward control, the HC can significantly improve performance as compared to a purely feedback control strategy. A proper definition of...journal article 2016

Kooijman, J.D.G. (author)Bicycle designers traditionally develop bicycles based on experience and trial and error. Adopting modern engineering tools to model bicycle and rider dynamics and control is another method for developing bicycles.
