Dear Editor, This letter studies a real-world issue in leader-follower multi-agent systems (MASs) named open topology, which permits the variations of agent set and network connections. Specially, a novel transition process is developed to explain how the involved variation of network scale affects the dynamic behavior of the MASs. From a resource limited perspective, the distributed saturated impulsive control is then designed, under which some sufficient criteria are integrated into local quasi-consensus performance. We also provide a combined optimization algorithm for all agents to make the estimated domain of initial errors closer to the real one, thereby resulting in less conservativeness. Finally, a numerical example validates our results.

With the widespread application of global navigation satellite system (GNSS), spoofing attacks pose a threat to the security and reliability of GNSS. It is of great significance to design effective GNSS spoofing detection technology to ensure the security and reliability of GNSS system applications for receiver users. Traditional spoofing detection techniques generally only determine whether a spoofing attack has occurred by monitoring the feature changes of one or two data information in the receiver. However, some spoofing modes can cleverly make the monitored data very close to the real data, thus avoiding these detection methods and easily making them ineffective. In this study, a GNSS spoofing jamming detection method based on hybrid kernel relevance vector machine (RVM) is proposed. The improved signal quality monitoring (SQM) movement variance, carrier noise ratio movement variance, pseudo range Doppler consistency, pseudorange residual, Doppler frequency, clock offset and clock drift are used as detection characteristics. This technology can detect GNSS spoofing signals, effectively improving the safety and reliability of GNSS systems. The experimental results show that this technology has high detection accuracy and anti-interference ability and can effectively respond to various forms of spoofing attacks.
随着全球卫星导航系统(GNSS)的广泛应用,欺骗攻击对GNSS的安全性和可靠性构成了威胁。设计有效的GNSS欺骗检测技术对于保证GNSS系统应用对接收机用户的安全性和可靠性具有重要意义。传统的欺骗检测技术一般只通过监测接收方中一个或两个数据信息的特征变化来判断是否发生欺骗攻击。然而,一些欺骗模式可以巧妙地使被监控的数据与真实数据非常接近,从而避开了这些检测方法,容易使其失效。提出了一种基于混合核相关向量机(RVM)的GNSS欺骗干扰检测方法。改进的信号质量监测(SQM)运动方差、载波噪声比运动方差、伪距离多普勒一致性、伪距残差、多普勒频率、时钟偏移和时钟漂移作为检测特征。该技术可以检测GNSS欺骗信号,有效提高GNSS系统的安全性和可靠性。实验结果表明,该技术具有较高的检测精度和抗干扰能力,能够有效应对各种形式的欺骗攻击。

In the industrial roller kiln, the time-delay characteristic in heat transfer causes the temperature field to be affected by both the current and historical temperature states. It presents a poor control performance and brings a significant challenge to the process precise control. Considering high complexity of precise modeling, a data-driven time-delay optimal control method for temperature field of roller kiln is proposed based on a large amount of process data. First, the control challenges and problem description brought by time-delay are demonstrated, where the cost function for the time-delay partial differential equation system is constructed. To obtain the optimal control law, the policy iteration in adaptive dynamic programming is adopted to design the time-delay temperature field controller, and neural network is used for the critic network in policy iteration to approximate the optimal time-delay cost function. The closed-loop system stability is proved by designing the Lyapunov function which contains the time-delay information. Finally, through establishing the time-delay temperature field model for roller kiln, the effectiveness and convergence of the proposed method is verified and proved.

This article presents an adaptive fault-tolerant tracking control strategy for unknown affine nonlinear systems subject to actuator faults and external disturbances. To address the hyperparameter initialization challenges inherent in conventional neural network training, an improved self-organizing radial basis function neural network (SRBFNN) with an input-dependent variable structure is developed. Furthermore, a novel self-organizing RBFNN-based observer is introduced to estimate system states across all dimensions. Leveraging the reconstructed states, the proposed adaptive controller effectively compensates for all uncertainties, including estimation errors in the observer, ensuring accurate state tracking with reduced control effort. The uniform ultimate boundedness of all closed-loop signals and tracking errors is rigorously established via Lyapunov stability analysis. Finally, simulations on two different nonlinear systems comprehensively validate the effectiveness and superiority of the proposed control approach.

Dear Editor, This letter addresses the Nash equilibrium seeking problem for games with second-order players subject to unknown input dead-zones and denial-of-service (DoS) attacks. By using ideas from the digital twin, a distributed Nash equilibrium seeking strategy is proposed. In the proposed strategy, the twin players are designed to be second-order integrators, based on which a distributed control law is provided so as to find the Nash equilibrium under DoS attacks. Moreover, adaptive control laws and sliding mode control laws are synthesized for the actual players such that they can track the twin players under unknown input dead-zones. Theoretical investigations show that the proposed strategy is effective to drive the actions of actual players to the Nash equilibrium under the given conditions. A numerical example is provided to verify the effectiveness of the proposed strategy.

Active Compression on Unknown Disturbance and Uncertainty via Extended State Observer 扩展状态观测器对未知干扰和不确定性的主动压缩

Extended state observer (ESO) is heavily limited by the unknown disturbance and its derivative, which requires high observing gains to decrease estimating error, resulting in serious noise sensitivity. To modify the disturbance estimation characteristics encountered by the observer, the active compression extended state observer (ACESO) is proposed in this study. The ACESO decreases the bound of residual lumped disturbance and its derivative by actively compressing the initial lumped disturbance, without relying on prior knowledge. The stability constraint and convergence results of ACESO are analyzed and compared with ESO theoretically. The results show that the ACESO mitigates the trade-off between noise sensitivity and high-gain observation. Benefiting from active compression, the ACESO has substantially less noise sensitivity than the ESO, while obtaining the same and even better estimating performance than the ESO. In addition, the nonlinear ACESO is discussed, which automatically balances the contradiction between estimation and convergence.

扩展状态观测器(ESO)受未知扰动及其导数的严重限制,需要较高的观测增益来减小估计误差,导致严重的噪声敏感性。为了改善观测器遇到的扰动估计特性,本文提出了主动压缩扩展状态观测器(ACESO)。ACESO通过主动压缩初始集总扰动来减小残余集总扰动及其导数的界,而不依赖于先验知识。从理论上分析了ACESO的稳定性约束和收敛性结果,并与ESO进行了比较。结果表明,ACESO减轻了噪声灵敏度和高增益观测之间的权衡。得益于主动压缩,ACESO具有比ESO低得多的噪声灵敏度,同时获得与ESO相同甚至更好的估计性能。此外,还讨论了自动平衡估计与收敛矛盾的非线性ACESO算法。仿真和实验验证了该方法的有效性。

To modify the disturbance estimation characteristics encountered by the observer, the active compression extended state observer (ACESO) is proposed in this study. The ACESO decreases the bound of residual lumped disturbance and its derivative by actively compressing the initial lumped disturbance, without relying on prior knowledge. The stability constraint and convergence results of ACESO are analyzed and compared with ESO theoretically. The results show that the ACESO mitigates the trade-off between noise sensitivity and high-gain observation. Benefiting from active compression, the ACESO has substantially less noise sensitivity than the ESO, while obtaining the same and even better estimating performance than the ESO. In addition, the nonlinear ACESO is discussed, which automatically balances the contradiction between estimation and convergence.

Complex autonomous dynamical systems require sophisticated optimization methods that encompass environment awareness, path planning, and decision-making. swarm intelligence algorithms, inspired by natural phenomena such as bird flocks and fish schools, have undergone significant advancements over recent decades. This paper provides a comprehensive review of particle swarm optimization (PSO) in the context of autonomous systems. We specifically examine the application of PSO to multi-agent dynamical systems, reviewing how PSO variants are employed to tackle diverse optimization challenges across various platforms, including ground vehicles, autonomous under-water vehicles, and unmanned aerial vehicles. Additionally, we delve into the use of PSO within swarm robotics and multi-agent systems. The paper concludes with an outline of potential future research directions, particularly focusing on the application of PSO to the multi-agent rendezvous problem in autonomous systems.
