Dear Editor,Two-dimensional(2-D) systems have wide applications in image data processing,gas absorption and fluid dynamics analysis [1]-[3].When there exist abrupt changes in 2-D systems,they are usually modeled by 2-D Markov jump systems(MJSs) or 2-D semi-Markov jump systems(SMJSs).This letter investigates the control of 2-D SMJSs based on a novel mode generation mechanism,which could avoid mode ambiguousness phenomenon caused by the evolution of system mode in two different *** criterion that guarantees the almost surely exponential stability of the system is obtained.A thermal process is studied to demonstrate the availability of the proposed method.

The paper sets and solves the problem of: the power unit power stabilization system in accordance with the specified value;and increasing the efficiency, parametric optimization of autonomous control systems was performed, both for conventional and prognostic ones, with an assigned stability margin for the minimum of the linear integral criterion. For a correct solution, the combined influence of one system on another through the object was taken into account. Modelling and research of the system with a static compensator from the fuel regulator to the feedwater flow regulator were carried out. It is shown that the connectivity of the system leads to the appearance to undesirable oscillations. To eliminate the drawback of conventional systems, it is proposed to switch to prognostic regulators. The object of the study is an 800 MW power unit. The dynamics are obtained on the basis of experimental data. © 2024 IEEE.

This paper studies the spectral properties of two important graph matrices in the literature, known as the leader-follower matrices. These two matrices arise from various cooperative control problems of multi-agent systems in a leader-follower architecture, and in most cases, they are the keys to the solvability of these cooperative control problems. In contrast with the existing results, which appeal to the algebraic graph theory and matrix analysis tools, we reveal the spectral properties from the viewpoint of dynamical systems. In particular, the spectral properties of the two graph matrices are derived by analyzing the convergence of a continuous-time and a discrete-time linear system, respectively. © 2024 Technical Committee on control Theory, Chinese Association of Automation.

Domain adaptation methods and appropriate feature extractors are usually applied to solve the problem that the variable working conditions of bearings affect the effectiveness of the fault diagnostic framework. However, the existing feature extractors are too complex to be deployed in real industries. In this paper, we propose a lightweight framework called improved depthwise separable convolution network (IDSCN) for the diagnosis of bearing faults in variable operating conditions. IDSCN is built on wavelet convolution and depthwise separable residual convolution (DSRC), where the wavelet convolution is used to extract frequency features from the source and target domains, and DSRC guarantees the performance of feature extraction with reduced parameters and computation. To minimise the distribution difference between the source and target domains, the local maximum mean difference is incorporated into the proposed framework. The performance of the proposed framework is validated on the Paderborn University dataset, involving a total of 6 transfer tasks. The experiment shows that the proposed framework achieves satisfactory results and outperforms other frameworks in bearing fault diagnosis. © 2025 IEEE.

Distributed Secure Consensus Estimation for Power systems Against False Data Injection Attacks

International Journal of Robust and Nonlinear control 2025年第11期35卷 4724-4737页

As a result of the rapid growth of distributed state estimation in modern power systems, power networks are facing increasingly serious security problems, thus requiring the advancement of defense techniques against cyber attacks. This paper is devoted to investigating distributed consensus state estimation with a defense mechanism against false data injection (FDI) attacks for power systems. By introducing a transformation matrix, the local subsystem model associated with the mixed remote terminal unit and phasor measurement unit measurements is constructed. Taking into account historical estimation information on state variables without being attacked, a defense mechanism constructed by secure historical estimation value is presented to protect the estimator against FDI attacks while maintaining accuracy in estimation. Then a distributed Kalman consensus filter (DKCF) is hosted to estimate the dynamic states of power systems under FDI attack protector. Considering scalability in large-scale power systems, a suboptimal DKCF with the designed protector is developed. By means of the Lyapunov-based approach, a sufficient condition is provided to ensure that the proposed estimator equipped with the defense mechanism is stable. Finally, the proposed distributed state estimation algorithms are validated on an IEEE benchmark 14-bus power system. © 2025 John Wiley & Sons Ltd.
