Dual Perspective Secure Analysis for Local Estimate-Based FDI Attacks in Networked Systems

This article discusses the security concerns related to networked systems, where the sensor sends the local estimate to the remote estimator, which may be attacked. Traditionally, in the remote state estimation with the innovation or raw measurement case, denial of service (DoS) and false data injection (FDI) attacks are investigated thoroughly. Notably, for remote state estimation with local estimate cases considered in this article, most existing works consider DoS attacks but not FDI attacks, negatively affecting remote state estimation performance. Furthermore, current detection mechanisms encounter challenges when identifying such attacks due to the unavailable innovation or raw measurement. As such, we study FDI attacks under this framework and provide the corresponding secure analysis using a dual-perspective approach. Specifically, we propose a detector to detect such attacks using the prior information extracted from the remote estimator. Then, we analyze the existence of stealthy attacks and characterize the corresponding performance evaluation for the remote estimation under such attacks. Following this, we construct the optimal attack scheme, maximizing the expected average and terminal estimation error covariances, respectively. To reduce the above vulnerability, we develop a co-design transmission strategy and offer an analytical detection performance evaluation under different attack scenarios. Finally, simulations are provided to illustrate the proposed results. © 2025 IEEE.

Laser-enhanced high-magnification telecentric imaging system for multiphase flow monitoring in membrane fouling

引用

Chinese Journal of Chemical engineering 2025年 82卷 25-38页

作者： Xu, Haohan Liang, Hu Feng, Xin Zhang, Weipeng Duan, Xiaoxia Chen, Jie Yang, Chao State Key Laboratory of Biochemical Engineering Institute of Process Engineering Chinese Academy of Sciences Beijing100190 China School of Chemical Engineering University of Chinese Academy of Sciences Beijing100049 China

Membrane fouling is the primary resistance to the continuous production of stirred membrane reactors. This work presents a laser-enhanced high-magnification telecentric imaging system (LEHTIS), which uses a high-magnification telecentric lens and laser-enhanced illumination to invasively capture the motion of particles on the membrane surface or near the membrane. The problems of working distance and particle interference in the stirred membrane reactor are solved to achieve the purpose of in-situ monitoring of membrane fouling. This method is suitable for high flow rates, high solid holdup, and small particle size systems, and the dynamic motion and accumulation of particles are preliminarily analyzed. It shows that the accumulation and desorption of particles on the membrane surface are related to the physical properties of the membrane surface. There is an intermittent rotational movement in the flow field near the membrane, and it tends to stabilize over time. The filtration process can be assessed by monitoring changes in the overall velocity and acceleration of particles near the membrane. The analysis of forces acting on individual particles is compared and validated with the force balance model to correct and accurately apply it to stirred membrane reactors. The development of LEHTIS provides an effective tool for in-situ monitoring of membrane fouling and optimizing the stirred membrane reactors for industrial applications. © 2025 The Chemical Industry and engineering Society of China, and Chemical Industry Press Co., Ltd.
