Liu, X. (author), Dabiri, A. (author), Xun, Jing (author), De Schutter, B.H.K. (author)This paper deals with the train scheduling problem for metro networks taking into account time-dependent passenger origin–destination demands and train speed profiles. The aim is to adjust train schedules online according to time-dependent passenger demands so that passenger satisfaction and operational costs are jointly optimized. An...journal article 2023

Meng, Z. (author), Liu, Qing feng (author), Ukrainczyk, Neven (author), Mu, Song (author), Zhang, Yufei (author), De Schutter, Geert (author)Cementitious materials exposed to marine and saline environments are commonly threatened by a combined attack of sulfate and chloride ions. This study developed a numerical framework to investigate two combined coupling mechanisms of 1) coupled solid-liquid chemical reactions for competitive chloride-sulfate attack and 2) electrostatic multi...journal article 2023

Cordiano, F. (author), Fochesato, Marta (author), Huang, Linbin (author), De Schutter, B.H.K. (author)We present a model predictive control framework for a class of nonlinear systems affected by additive stochastic disturbances with (possibly) unbounded support. We consider hard input constraints and chance state constraints and we employ the unscented transform method to propagate the disturbances over the nonlinear dynamics in a...journal article 2023

Sun, D. (author), Jamshidnejad, A. (author), De Schutter, B.H.K. (author)We propose a novel method to improve the convergence performance of model predictive control (MPC) for setpoint tracking, by introducing sub-references within a multilevel MPC structure. In some cases, MPC is implemented with a short prediction horizon due to limited on-line computation capacity, which could lead to deteriorated dynamic...journal article 2023

(author)Surrogate Safety Measures (SSMs) are used to express road safety in terms of the safety risk in traffic conflicts. Typically, SSMs rely on assumptions regarding the future evolution of traffic participant trajectories to generate a measure of risk, restricting their applicability to scenarios where these assumptions are valid. In response to...journal article 2023

Sun, Yubo (author), Ghorbani, Saeid (author), Ye, G. (author), De Schutter, Geert (author)Alkali-activated material (AAM) is developed as a green alternative binder to replace Portland cement (PC) in the construction field. However, the large-scale application with AAM concrete is limited so far, with the insufficient knowledge of rheological behavior being a major obstruct. Thixotropy of concrete is of great interest, which can...book chapter 2023

Jeschke, J.M. (author), Sun, D. (author), Jamshidnejad, A. (author), De Schutter, B.H.K. (author)While Model Predictive Control (MPC) is a promising approach for network-wide control of urban traffic, the computational complexity of the, often nonlinear, online optimization procedure is too high for real-time implementations. In order to make MPC computationally efficient, this paper introduces a parameterized MPC (PMPC) approach for...journal article 2023

Wang, X. (author), Baldi, S. (author), Feng, Xuewei (author), Wu, Changwei (author), Xie, Hongwei (author), De Schutter, B.H.K. (author)The vector field method was originally proposed to guide a single fixed-wing Unmanned Aerial Vehicle (UAV) towards a desired path. In this work, a non-uniform vector field method is proposed that changes in both magnitude and direction, for the purpose of achieving formations of UAVs. As compared to related work in the literature, the...journal article 2023

Ubbens, Martiene (author), De Schutter, B.H.K. (author)Two optimization-based approaches are proposed to optimize the power routing and turbine setpoints of offshore wind farm (OWF) collector systems during cable outages. The open-loop control strategy assumes that the network can only be reconfigured at the beginning of the outage. In contrast, the receding horizon control strategy is deployed...conference paper 2023

de Araujo Passos, L.A. (author), Ceha, T.J. (author), Baldi, S. (author), De Schutter, B.H.K. (author)Controlling the operation of HVAC (Heating, Ventilation, and Air-Conditioning) systems is arguably the most effective way to reach desired indoor conditions in buildings. Nevertheless, such control may involve complex dynamics when dealing with passive energy technologies. In this paper, we focus on maximizing the passive operation of HVAC in...journal article 2023

(author)Predictive maintenance scheduling of modular-multilevel-converters (MMCs) requires estimations of the failure probabilities of MMCs during a period of time in the future. Particularly, the predicted future failure probabilities are influenced by two main factors, the mission profiles of the MMCs and the maintenance decisions on the MMCs...journal article 2023
