Yu, Xinghuo (author), Tang, Changbing (author), Palensky, P. (author), Colombo, Armando (author)Imagine you want to send money to a friend overseas. Wouldn't it be good if you didn't have to pay hefty fees to the intermediaries, and your friend received the funds very quickly? Now imagine ordering parts to make a product in your manufacturing plant. Wouldn't it be great if you were able to verify where each part comes from and have...journal article 2022

Wang, Y. (author), Yu, Rongjie (author), Qiu, Shuhan (author), SUN, J. (author), Farah, H. (author)Highly automated vehicles (HAVs) have been introduced to the transportation system for the purpose of providing safer mobility. Considering the expected long co-existence period of HAVs and human-driven vehicles (HDVs), the safety operation of HAVs interacting with HDVs needs to be verified. To achieve this, HAVs' Operational Design Domain ...journal article 2022

Liu, Di (author), Besselink, Bart (author), Baldi, S. (author), Yu, Wenwu (author), Trentelman, Harry L. (author)Despite the progress in the field of longitudinal formations of automated vehicles, only recently an interpretation of longitudinal platooning has been given in the framework of disturbance decoupling, i.e. the problem of making a controlled output independent of a disturbance. The appealing feature of this interpretation is that the...journal article 2022

Yu, Y. (author), Shekhar, A. (author), Chandra Mouli, G.R. (author), Bauer, P. (author)This paper benchmarks the performance of three practical electric vehicle (EV) charging scheduling methods relative to uncontrolled charging (UNC) in low-voltage (LV) distribution grids. The charging methods compared are the voltage droop method (VDM), price-signal-based method (PSM) and average rate method (ARM). Trade-offs associated with the...journal article 2022

Chen, Cong (author), Batselier, K. (author), Yu, Wenjian (author), Wong, Ngai (author)Tensor, a multi-dimensional data structure, has been exploited recently in the machine learning community. Traditional machine learning approaches are vector- or matrix-based, and cannot handle tensorial data directly. In this paper, we propose a tensor train (TT)-based kernel technique for the first time, and apply it to the conventional...journal article 2022

Hong, Huifen (author), Baldi, S. (author), Yu, Wenwu (author), Yu, Xinghuo (author)This article investigates the distributed time-varying optimization problem for second-order multiagent systems (MASs) under limited interaction ranges. The goal is to seek the minimum of the sum of local time-varying cost functions (CFs), where each CF is only available to the corresponding agent. Limited communication range refers to the...journal article 2022

Li, Lingjie (author), Yu, Wenjian (author), Batselier, K. (author)In recent years, the application of tensors has become more widespread in fields that involve data analytics and numerical computation. Due to the explosive growth of data, low-rank tensor decompositions have become a powerful tool to harness the notorious curse of dimensionality. The main forms of tensor decomposition include CP...journal article 2022

Shi, W. (author), Dong, J. (author), Soeiro, Thiago B. (author), Riekerk, C. (author), Grazian, F. (author), Yu, G. (author), Bauer, P. (author)Due to the urgent desire for a fast, convenient, and efficient battery charging technology for electric vehicle (EV) users, extensive research has been conducted into the design of high-power inductive power transfer (IPT) systems. However, there are few studies that formulate the design as a multiobjective optimization (MOO) research...journal article 2022

Cai, Yuxin (author), Liu, Qing feng (author), Yu, Linwen (author), Meng, Zhaozheng (author), Hu, Zhe (author), Yuan, Qiang (author), Šavija, B. (author)Fresh concrete needs vibration to compact, fill the mould and reach a dense state. During the compaction process, coarse aggregates (CAs) tend to settle, affecting the homogeneity and eventually the long-term durability of hardened concrete. In this study, a 3-D, multi-phase numerical model for fresh concrete is developed for better...journal article 2021

Lv, Maolong (author), Yu, Wenwu (author), Baldi, S. (author)This paper proposes a novel set-invariance adaptive dynamic surface control (DSC) design for a larger class of uncertain large-scale nonlinear input-saturated systems. The peculiarity of this class is that no a priori bound on the continuous control gain functions is assumed (i.e., their boundedness cannot be assumed before obtaining system...journal article 2021
