(author)Prescribed-performance control (PPC) for high-power dynamics with time-varying unknown control coefficients requires to address two open problems: (a) given a Nussbaum function, which properties hold for the power of the Nussbaum function? (b) to avoid high gains, how to design a switching gain that increases only when the tracking error is...journal article 2022

Liu, X. (author), Dabiri, A. (author), De Schutter, B.H.K. (author)Timetable scheduling plays a key role in daily operations of urban rail transit systems, as it determines the quality of service provided to passengers. In order to develop efficient timetable scheduling methods, it is necessary to develop a proper model to integrate timetable-related and passenger-related factors in urban rail network...conference paper 2022

Sun, Beibei (author), Ye, Guang (author), De Schutter, Geert (author)Alkali-activated materials(AAM) are known to be environmentally friendly alternatives to cement-based materials because they can potentially reduce greenhouse gas emissions and reutilize industrial by-products. However, the application of AAM is still limited by the lack of mixture design regulation. Unlike cement, the very different chemical...conference paper 2021

Qiu, Xiujiao (author), Chen, Jiayi (author), Ye, Guang (author), De Schutter, Geert (author)ASR (alkali-silica reaction) is one of the toughest durability problems in engineering. However, the damage induced by ASR is still fairly unpredictable due to the lack of microstructural information of cement-based materials affected by ASR, while the microstructure determines the global performance. In order to fill this gap, a multiscale...conference paper 2021

Van Der Putten, J. (author), Snoeck, D. (author), De Schutter, G (author), Van Tittelboom, K. (author)Nowadays, 3D printing of cementitious materials is a hot research topic in the construction industry. This construction method is capable of producing complex geometries and largescale components without the use of expensive formwork. However, due to the lack of molding, more shrinkage will be induced and the amount of cracks will increase. As...conference paper 2021

Yang, Kai (author), Ye, Guang (author), De Schutter, Geert (author)Water molecules exist as two spin isomers, differing by the relative orientation of the nuclear spins of the two hydrogen atoms: either antiparallel (para-water, S=0) or parallel (ortho-water, S=1) [1]. The transition between these nuclear spin states can be achieved through magnetic symmetry breaking via a field gradient across the spins...conference paper 2021

(author)In order to better understand the stochastic dynamic features of signalized traffic networks, we propose a Markov traffic model to simulate the dynamics of traffic link flow density for signalized urban traffic networks with demand uncertainty. In this model, we have four different state modes for the link according to different congestion...journal article 2021

Jeschke, J.M. (author), De Schutter, B.H.K. (author)Model Predictive Control (MPC) has shown promising results in the control of urban traffic networks, but unfortunately it has one major drawback. The, often nonlinear, optimization that has to be performed at every control time step is computationally too complex to use MPC controllers for real-time implementations (i.e. when the online...journal article 2021

Fu, J. (author), Nunez, Alfredo (author), De Schutter, B.H.K. (author)Preventive maintenance is applied in distribution networks to prevent failures by performing maintenance actions on components that are at risk. Distributed generators (DGs) and batteries can be used to support power to nearby loads when they are isolated due to maintenance. In this paper, a novel short-term preventive maintenance method is...journal article 2021

Yue, D. (author), Baldi, S. (author), Cao, Jinde (author), Li, Qi (author), De Schutter, B.H.K. (author)In this article, the time-varying formation and time-varying formation tracking problems are solved for linear multiagent systems over digraphs without the knowledge of the eigenvalues of the Laplacian matrix associated with the digraph. The solution to these problems relies on an approach that generalizes the directed spanning tree (DST)...journal article 2021

Lv, Maolong (author), De Schutter, B.H.K. (author), Yu, Wenwu (author), Baldi, S. (author)This article addresses and solves the adaptive asymptotic tracking for a class of uncertain switched positive linear dynamics (also known in the literature as compartmental models) subject to dwell-time constraints. Compared to the state-of-the-art, the innovative feature of this method is to attain for the first time asymptotic set-point...journal article 2021

Lago, Jesus (author), Poplavskaya, K. (author), Suryanarayana, Gowri (author), De Schutter, B.H.K.

In several countries, it is forbidden to influence the grid imbalances in order to let the TSO retain full control of grid regulation. In this...journal article 2021
