With the rapid progress of technology, the application of unmanned aerial vehicles (UAVs) has become widespread in various civilian and military activities. The research on fault diagnosis during a flight is a critical step towards enhancing the safety of UAV systems. Swarm-inspired heuristic algorithms have attracted significant attention owing to their fast iteration speed and strong optimization capabilities. This paper proposes a UAV fault diagnosis method based on the slime mold algorithm (SMA) under the condition of imbalanced data, thus addressing the issue of low diagnostic accuracy caused by a significantly longer normal flight time compared to the fault flight time in UAV operations. Using a real-world dataset of UAV flight faults with multiple fault patterns, the proposed approach optimizes the parameters of the support vector machine through SMA, thereby improving the fault diagnosis performance during actual UAV flights. © 2023 IEEE.

Progress in Natural science:Materials International 2025年第1期35卷 166-176页

作者： Jianlu Li Yanming Chen Tongxing Lei Jianguo Liu Guizheng Liu Zhaoyang Deng Xuebiao Wu Zhiyu Ding Yinghe Zhang Junwei Wu Yanan Chen Guangzhou Automobile Group Co. Ltd. School of Materials Science and Engineering Harbin Institute of Technology School of Materials and Environmental Engineering Shenzhen Polytechnic University School of Science Shenzhen Key Laboratory of Flexible Printed Electronics Technology Shenzhen Key Laboratory of Advanced Functional Carbon Materials Research and Comprehensive Application Harbin Institute of Technology School of Materials Science and Engineering Key Laboratory of Advanced Ceramics and Machining Technology of Ministry of Education Tianjin Key Laboratory of Composite and Functional Materials Tianjin University

A data-driven framework with strong generalization capabilities is proposed to effectively extract features and easily access battery capacity. This framework can make highly accurate predictions for the battery capacities of plug-in electric vehicles. The feature extraction process is entirely based on statistics, which are always available and can be generalized to various types of battery data. An improved ampere-hour integral method can easily access battery capacity with just short-charging segments lasting 500 s. Several machine-learning models are trained to verify the framework's effectiveness, with the best model achieving a test error of 0.84 % based on leave-one-out validation. SHAP values are used to provide a reasonable interpretation of the relationships between the constructed features and model outputs. The proposed framework offers advantages such as reduced computational resources, wide generalization, and high prediction accuracy, showing great potential for battery management.

Sustainable Carbon-Based Catalyst Materials Derived From Lignocellulosic Biomass for Energy Storage and Conversion: Atomic Modulation and Properties Improvement

引用

Carbon Energy 2025年第5期7卷 59-104页

Carbon electrocatalyst materials based on lignocellulosic biomass with multi-components, various dimensions, high carbon content, and hierarchical morphology structures have gained great popularity in electrocatalytic applications recently. Due to the catalytic deficiency of neutral carbon atoms, the usage of single lignocellulosic-based carbon materials in electrocatalysis involving energy storage and conversion presents unsatisfactory applicability. However, atomic-level modulation of lignocellulose-based carbon materials can optimize the electronic structures, charge separation, transfer processes, and so forth,which results in substantially enhanced electrocatalytic performance of carbon-based catalysts. This paper reviews the recent advances in the rational design of lignocellulosic-based carbon materials as electrocatalysts from an atomic-level perspective,such as self/external heteroatom doping and metal modification. Then, through systematic discussion of the design principles and reaction mechanisms of the catalysts, the applications of the prepared lignocellulosic-based catalysts in rechargeable batteries and electrocatalysis are reviewed. Finally, the challenges in improving the catalytic performance of lignocellulosicbased carbon materials as electrocatalysts and the prospects in diverse applications are reviewed. This review contributes to the synthesis strategy of lignocellulose-based carbon electrocatalysts via atomic-level modulation, which in turn promotes the lignocellulose valorization for energy storage and conversion.
