Chung, Chris (author)Loss-of-Control (LoC) is the primary cause of drone crashes, necessitating efficient onboard prevention systems that are effective in terms of sensor requirements, computing power, and memory. This study introduces a data-driven approach for detecting LoC in quadrotors, using Critical Slowing Down (CSD) theory as an Early Warning Signal (EWS) of...master thesis 2024

Wu, J. (author), Li, S. (author), Fu, A. (author), Cvetkovic, M. (author), Palensky, P. (author), Vasquez, Juan C. (author), Guerrero, Josep M. (author)The increasing proportion of renewable energy introduces both long-term and short-term uncertainty to power systems, which restricts the implementation of energy management systems (EMSs) with high dependency on accurate prediction techniques. A hierarchical online EMS (HEMS) is proposed in this paper to economically operate the Hybrid...journal article 2024

Munster, Marcel (author)An aging population puts a pressure on health-care workers working with dementia patients globally. A potential solution is to provide care with Socially Assistive Robots (SARs), i.e. robots who help people through social interaction. However, for effective care these SARs must be able to personalize their behavior to individual patients and...master thesis 2023

de Koning, C.M.M. (author), Jamshidnejad, A. (author)Search-and-rescue (SaR) in unknown environments is a crucial task with life-threatening risks. SaR requires precise, optimal, and fast decisions to be made. Robots are promising candidates expected to execute various SaR tasks autonomously. While humans use heuristics to effectively deal with uncertainties of SaR, optimisation of multiple...journal article 2023

Singh, Diwakar (author), Sharma, S. (author), Kumar, Rajeev (author), Chauhan, Vishal S. (author), Vaish, Rahul (author)Although conventional actuators like piezoelectric and electrostrictive are efficient, but they required hard wiring, which contaminates the control signal and adds to the weight of the structure. The current study presents a wireless control strategy using photostrictive actuators. Owing to the fortunate combination of photovoltaic effect...journal article 2023

Wu, Jingxuan (author), Li, Shuting (author), Gui, Yonghao (author), Cvetkovic, M. (author), Vasquez, Juan C. (author), Guerrero, Josep M. (author)A fuzzy logic based online energy management system (FLEMS) is designed in this paper to achieve the optimal electricity cost in a residential Microgrid (MG). The proposed FLEMS is combined by a local energy price model (LEPM) and a fuzzy-logic strategy. The LEPM will preprocess the sampling data to estimate the electricity market and local MG...conference paper 2023

Zuo, Renwei (author), Li, Yinghui (author), Lv, Maolong (author), Liu, Zongcheng (author), Zhang, Fan (author)This article proposes an output-feedback fixed-time trajectory tracking control methodology for hypersonic flight vehicles subject to asymmetric output constraints. In contrast to the state of the art, the most distinguishing feature of our control design lies in avoiding using conventional recursive design methods (e.g., backstepping...journal article 2022

Dell'Anna, D. (author), Jamshidnejad, A. (author)Socially Assistive Robots (SARs) are increasingly used in dementia and elderly care. In order to provide effective assistance, SARs need to be personalized to individual patients and account for stimulating their divergent thinking in creative ways. Rule-based fuzzy logic systems provide effective methods for automated decision-making of SARs...journal article 2022

De Iuliis, Melissa (author), Kammouh, O. (author), Cimellaro, Gian Paolo (author)Due to the increasing frequency of natural and man-made disasters, the scientific community has paid considerable attention to the concept of resilience engineering. On the other hand, authorities and decision-makers have been focusing their efforts on developing strategies that can help increase community resilience to different types of...journal article 2022

Wu, Jiansong (author), Xing, Yuxuan (author), Bai, Yiping (author), Hu, Xiaofeng (author), Yuan, S. (author)Accidents induced by natural disasters at sports sites may cause catastrophic loss of great concern. However, previous studies on risk assessments of sports sites have only focused on operational risk and equipment failure. With the frequent occurrence of extreme disasters, the risk of domino chains caused by natural disasters at large-scale...review 2022

Lv, Maolong (author), Li, Yongming (author), Pan, W. (author), Baldi, S. (author)This article proposes a fuzzy adaptive design solving the finite-time constrained tracking for hypersonic flight vehicles (HFVs). Actuator dynamics and asymmetric time-varying constraints are considered when solving this problem. The main features of the proposed design lie in 1) introducing a novel piecewise but differentiable switching...journal article 2022

Maathuis, E.C. (author), Pieters, W. (author), van den Berg, Jan (author)Cyber operations are relatively a new phenomenon of the last two decades. During that period, they have increased in number, complexity, and agility, while their design and development have been processes well kept under secrecy. As a consequence, limited data(sets) regarding these incidents are available. Although various academic and...journal article 2020
