Yue, Dongdong (author), Baldi, S. (author), Cao, Jinde (author)We revisit distributed sampled-data consensus problems from a scalability point of view. Existing solutions in the literature for estimating the maximum sampling interval that preserves stability rely on the Lyapunov functional method. With this method, the overall closed-loop system (i.e. the overall network of agents) is treated as a time...journal article 2023

Čustović, I. (author), Cao, Jianpeng (author), Hall, Daniel M. (author)More widespread use of industrialized construction (IC) is hampered by the high capital cost of advanced production facilities paired with low profit margins. A novel service-oriented cloud manufacturing (CMfg) model could in theory increase utilization and profitability of distributed production facilities. However, little research has...journal article 2023

Yue, Dongdong (author), Baldi, S. (author), Cao, Jinde (author), Li, Qi (author), De Schutter, B.H.K. (author)This paper addresses distributed adaptive optimal resource allocation problems over weight-balanced digraphs. By leveraging state-of-the-art adaptive coupling designs for multiagent systems, two adaptive algorithms are proposed, namely a directed-spanning-tree-based algorithm and a node-based algorithm. The benefits of these algorithms are...journal article 2023

Wen, Weijie (author), Lyu, Rui (author), Li, Botong (author), Cao, Hong (author), Yu, Jiali (author), Li, Bin (author), Popov, M. (author)For the black start-up of DC micro-grids, three-phase charging resistors are required to limit the uncontrollable surge current. The main drawback of this start-up method is the difficulty in determining the appropriate resistance value to achieve a rapid start-up and limit the surge current with the change of grid parameters. To address this...journal article 2023

Cao, Zhi (author), Huang, Yunkai (author), Guo, Baocheng (author), Peng, Fei (author), Dong, J. (author), Hemeida, Ahmed (author)To facilitate the active magnetic bearing (AMB) design and analysis, an accurate and fast model that considers both rotor eccentricity and the saturation effect is necessary. In this article, a novel hybrid analytical model (HAM) for effective calculation of the magnetic field of the AMB is proposed. Eccentricity and local saturation are...journal article 2022

Yue, Dongdong (author), Baldi, S. (author), Cao, Jinde (author)In this paper, we revisit the problem of consensus disturbance rejection for multiagent systems over a digraph, but from a different perspective, i.e., the perspective of a directed spanning tree (DST). When the minimum nonzero real part of the Laplacian eigenvalues is available, we reproduce the sufficient lower bound for a static...conference paper 2022

Cao, C.S. (author), Blaise, Agathe (author), Verwer, S.E. (author), Rebecchi, Filippo (author)These days more companies are shifting towards using cloud environments to provide their services to their client. While it is easy to set up a cloud environment, it is equally important to monitor the system's runtime behaviour and identify anomalous behaviours that occur during its operation. In recent years, the utilisation of Recurrent...conference paper 2022
