作者： Zhang, Qian Guo, Ge Northeastern University College of Information Science and Engineering Shenyang110819 China Northeastern University State Key Laboratory of Synthetical Automation for Process Industries Shenyang110819 China Northeastern University at Qinhuangdao School of Control Engineering Qinhuangdao066004 China

This paper studies the problem of cooperative lateral-longitudinal control for a collection of vehicles. To eliminate the limitation of zero initial spacing errors, a novel spacing policy is introduced. Then, a fast vehicular cooperative control method is proposed based on the new spacing policy, which can ensure internal stability, string stability and traffic flow stability. The algorithm is derived via the use of sliding mode control with a predefined-time terminal sliding mode surface. The efficiency and feasibility of the algorithm are demonstrated by numerical simulations. © 1967-2012 IEEE.

IEEE Transactions on Network science and engineering 2025年

作者： Chang, Zhenyu Zong, Guangdeng Wang, Wencheng Yue, Ming Zhao, Xudong Tiangong University School of Control Science and Engineering Tianjin300387 China Weifang University College of Machinery and Automation Weifang261061 China Dalian University of Technology School of Automotive Engineering Dalian116024 China Dalian University of Technology Faculty of Electronic Information and Electrical Engineering Dalian116024 China

This study addresses the formation control problem of under-actuated unmanned surface vehicle (USV) swarm systems and designs an obstacle avoidance strategy for navigating in obstacle environments. The intermittent communication scheme, consisting of the working period and the rest period, is introduced to reduce the communication burden and the consumption of control resources. A distributed formation control strategy is designed to guarantee the realization of the desired formation configuration. Considering the potential impact of obstacles in the operating environment, the artificial potential field repulsion obstacle avoidance method is embedded into the formation control strategy. To eliminate the impact of exogenous disturbances, a disturbance observer is established using the partially known disturbance information. Sufficient conditions are provided to ensure the uniformly ultimate boundedness of the formation error and disturbance observation error. In addition, an energy function related to the obstacle position information is designed to verify that the desired obstacle avoidance behavior can be achieved. The feasibility of theoretical analysis is validated by applying the developed control strategy to surface formation cruise missions. © 2013 IEEE.

The data-driven attack detection and resilient control problems for heterogeneous nonlinear nonaffine multi-agent systems (MASs) in the presence of false data injection (FDI) attacks are investigated in this paper. The heterogeneous nonlinear nonaffine MASs are firstly translated to an equivalent linear data model by using the dynamic linearization method. Then, based on the obtained linear data model, a novel attack detector, by using the nonlinear autoregressive with exogenous input neural network (NARXNN), is designed to detect whether MASs are under FDI attacks. Further, a data-driven resilient switched control scheme with the attack compensation mechanism is designed to achieve the leaderless consensus control objective. Finally, a simulation is given to illustrate the efficiency of the proposed method by comparisons. © 2013 IEEE.

Average Communication Rate for Networked Event-Triggered Stochastic control Systems

引用

IEEE Transactions on control of Network Systems 2025年

作者： Zhang, Zengjie Liu, Qingchen Mamduhi, Mohammad H. Hirche, Sandra Eindhoven University of Technology Department of Electrical Engineering Netherlands University of Science and Technology of China Department of Automation Hefei China University of Birmingham School of Computer Science United Kingdom Technical University of Munich Chair of Information-Oriented Control Munich Germany

Quantifying the average communication rate (ACR) of a networked event-triggered stochastic control system (NET-SCS) with deterministic thresholds is challenging due to the non-stationary nature of the system's stochastic processes. For a NET-SCS, the propagation of nonlinear statistics of the network communication status brought up by deterministic thresholds makes the precise computation of ACR difficult. Previous work used to over-simplify the computation using a Gaussian distribution without incorporating this nonlinearity, leading to sacrificed precision. This paper proposes a novel approach to calculate the exact ACR for a NET-SCS using a recursive model. We use theoretical analysis and a numerical study to qualitatively evaluate the deviation gap of the conventional approach that ignores the side information. The accuracy of our proposed method, alongside its comparison with the simplified results of the conventional approach, is validated by experimental studies. Our work is promising to benefit the efficient resource planning of networked control systems with limited communication resources by providing accurate ACR computation. © 2025 IEEE.

Node-Decomposition Privacy-Preserving for Finite-Time Secondary control of DC Microgrids

引用

IEEE Transactions on Smart Grid 2025年

作者： Wu, Han Zhu, Si-Min Chai, Li Zhu, Zhen-Hua Tian, Yu-Chu Wuhan University of Science and Technology Engineering Research Center of Metallurgical Automation and Measurement Technology School of Artificial Intelligence and Automation Wuhan430081 China Zhejiang University State Key Laboratory of Industrial Control Technology College of Control Science and Engineering Hangzhou310027 China Huzhou Institute of Industrial Control Technology Huzhou China Queensland University of Technology School of Computer Science BrisbaneQLD4001 Australia

In the distributed secondary control of DC microgrids, achieving both rapid convergence and robust information security is critical for enhancing control performance and maintaining power quality. However, current privacy-preserving approaches often compromise either control performance or privacy preservation performance. To address this challenge, this paper presents a node-decomposition privacy-preserving (NDPP) method for fully distributed, finite-time secondary control in DC microgrids. By splitting each node in the communication graph into multiple sub-nodes, the method enhances both convergence speed and privacy preservation without sacrificing control accuracy. Sub-nodes communicate within groups, and the topology of the generated graph is concealed from malicious nodes and eavesdroppers. Theoretical analysis is provided to prove finite-time voltage regulation and current sharing with privacy preservation against malicious nodes and external eavesdroppers. Simulations are conducted to verify the effectiveness of the method in maintaining control performance and power quality. © 2010-2012 IEEE.

Observer-based SMC for Discrete Interval Type-2 Fuzzy Semi-Markov Jump Models

IEEE Transactions on Fuzzy Systems 2025年

This study is devoted to the observer-based sliding mode control (SMC) for discrete nonlinear semi-Markov jump models with incomplete sojourn information and application to the quarter-car suspension model. The nonlinear plant with parameter uncertainty is represented by an interval type-2 fuzzy model, where the membership functions of the fuzzy rules are related to the system mode. Since sojourn information is challenging to obtain in practice, the sojourn time probability density function is considered to be incompletely available. The considered system is more general, not only relaxing the traditional assumption that all the sojourn time probability density functions are completely available but also covering completely available sojourn time probability density functions as a special case. The main innovation is that an observer-based SMC scheme is designed, which makes the discrete nonlinear models have better dynamic performance, and realizes the reachability of discrete quasi-sliding mode. By the interval type-2 fuzzy and classical Lyapunov function, the mean-square stability criterion of the semi-Markov jump models is constructed employing additional matrix variables. Then, an observer-based SMC mechanism is constructed to achieve the reachability of the quasi-sliding mode. Ultimately, the proposed method is validated by a two-degree-freedom quarter-car suspension model. © 2025 IEEE.

Estimating Battery Life from First-cycle Charging Data using HiLoSegNet model

In electric vehicles, some short-life lithium-ion batteries with a comparatively higher aging rate could adversely affect the service life of the large-scale battery pack. This study proposes the use of first-cycle charging data to estimate the battery life, providing an effective indicator for battery grouping. Herein, twelve features were extracted based on the battery’s first-cycle charging data. Random forest (RF) was used to quantify the Gini impurity variation in each feature regarding the battery life, and key features were accordingly selected. Aiming at the problem of less data in the first cycle, random noise was introduced to form spurious data based on the training dataset to increase the number and diversity of training samples. Owing to relatively small differences in the charging data of different batteries in the first cycle, the high-dimensional mapping technology, regular segmentation, and local decision-making were combined to establish a model called High-Dimensional Local Segmentation Network (HiLoSegNet), which was applied to small samples. By employing high-dimensional mapping, regular segmentation mechanism, and local regression analysis, the model enhances prediction accuracy and generalization capability in the presence of sparse features. The HiLoSegNet estimation model was pseudo-trained based on pseudo data and fine-tuned based on actual features. Two sets of NCA and NCM data from Tongji University were used as research objects to verify the proposed method. Among them, the maximum error, minimum error, root mean square error (RMSE), mean absolute error (MAE), and R-Square (R2) between the estimated battery life and actual value corresponding to the NCM dataset were found to be 7.6667, 0.2334, 5.2541, 4.8333, and 0.90, respectively. The method proposed in this study, which take 1.2 s without additional battery testing, can provide battery life indicators for battery grouping. © 2015 IEEE.

Multimodal-oriented Interactive Joint Source-Channel Coding for Lightweight Semantic Communication

引用

IEEE Transactions on Vehicular Technology 2025年

As a pivotal technology for sixth-generation (6G) mobile networks, semantic communication (SC) aims to enable low-energy, high-efficiency intelligent communication through joint source-channel coding (JSCC). However, current multimodal SC systems experience semantic divergence and conflicts due to imbalances in the representation capacity of individual encoders. Furthermore, high computational demands significantly elevate the deployment and operational costs of SC. In this letter, we propose a multimodal-oriented lightweight SC system based on an interactive JSCC scheme, promoting the evolution of 6G towards a multi-source collaboration paradigm. Additionally, a dynamic resource allocation method is introduced, which hierarchically adjusts computational costs to improve efficiency. Simulation results demonstrate that the proposed system reduces computational overhead by 60\% compared to six benchmarks while maintaining high performance and robustness in multiple tasks. © 1967-2012 IEEE.

齿轮装配误差会导致系统振动和噪声增大，影响系统的稳定性。这种影响可以通过齿轮微观修形得到补偿。首先，提出了一种考虑微观修形和耦合装配误差的改进三维轮齿加载接触分析(3D-LTCA)方法，并利用MASTA软件以及三个案例验证了该方法的准确性；其次，基于BP神经网络建立修形参数与啮合力学参数之间映射的代理模型(SM)，验证其有效性性，并将建立的代理模型与常用的Kriging、支持向量回归(SVR)、多项式回归响应面法(RSM)等代理模型进行了对比，从而进一步说明了本文代理模型的优越性；最后，引入SM建立以啮合刚度波动最小和啮合表面载荷分布更均匀为目标的优化模型。结果表明，即使考虑网络训练时间，通过代理模型优化齿轮副的效率仍远高于LTCA方法。优化后，带耦合装配误差的齿轮副的啮合刚度波动减小了34.10%，啮合面左右区域的平均接触应力差减小了62.84%。
