A Hierarchical Spatio-Temporal Graph Attention Network for False Data Injection Attack Detection in Smart Grids Hongjie Zhang, Jichuan Cheng, Xue Bai, Dong Wang, Rixin Gao, et al. Processes, 2026 The increasing digitalization of smart grids has made them vulnerable to false data injection attacks (FDIAs), which can bypass traditional bad data detection (BDD) schemes and compromise grid security. While machine learning offers promising detection capabilities, existing methods often struggle with generalization, interpretability, and the effective integration of the grid’s inherent spatio-temporal properties. To address these challenges, this paper presents a hierarchical spatio-temporal graph attention network (HST-GAT) for FDIA detection in smart grids. The proposed FDIA detection method employs a dedicated two-stage architecture. First, a graph attention network (GAT) explicitly captures the complex spatial dependencies and physical constraints of the grid topology. Second, a temporal module with multi-head self-attention and a gated recurrent unit (GRU) analyzes evolving attack patterns across time steps. This hierarchical separation ensures a more interpretable and physically grounded representation of cyber intrusions compared to joint spatio-temporal models. Explainability analysis using the SHapley Additive exPlanations (SHAP) method reveals the decision-making process of the proposed FDIA detection method, validating its alignment with the grid topology and identifying the key buses that influence its predictions. The results confirm the robustness of the proposed method and its value in improving cybersecurity in modern smart grids.
Adaptive dual-layer performance guaranteed sliding mode control for VSWT with EWS prediction Xuguo Jiao, Hao Luo, Guozhong Wang, Haoran Zhao, Wenchao Meng, et al. Transactions of the Institute of Measurement and Control, 2026 The maximum power point tracking (MPPT) control is a challenging task in wind power technology due to the stochastic and intermittent nature of the wind speed. This study proposes an effective wind speed (EWS) prediction-assisted adaptive performance guaranteed sliding mode controller to improve power capture efficiency for variable-speed wind turbines (VSWT). First, we propose a novel EWS estimation model based on a broad learning system (BLS). The model is trained on data collected from the existing supervisory control and data acquisition (SCADA) system. Furthermore, a BLS-based EWS prediction approach is developed to compensate for time delays present in the estimated EWS time-series. This prediction model can forecast the EWS in real-time to determine the optimal power reference for MPPT. Moreover, to deal with the uncertainties and external disturbances inherent in wind turbine systems and enhance the transient and steady-state performance of the MPPT control scheme, an error transformation technique-based sliding mode controller is developed. Dual-layer adaptation laws are formulated for the switching gain associated with the proposed sliding mode controller to compensate for the uncertainties appropriately and reduce the chattering phenomena. Finally, the FAST (Fatigue, Aerodynamics, Structures, and Turbulence) software is employed to verify the performance of the proposed approach.
Indoor Height Estimation Method for Scissor Lift Based on Sensor Information Fusion Xinhui Song, Yuzhe Li, Qinmin Yang, Bo Fan Proceedings of 2025 3rd International Conference on Communication Networks and Machine Learning Cnml 2025, 2025 Accurate height information is crucial for enhancing the safety and operability of scissor lift in indoor operations. To address issues such as outlier interference, integral drift, and barometric pressure perturbation in existing single-sensor height measurement methods, this paper proposes a height estimation algorithm that fuses accelerometer and barometer data. The dynamic threshold outlier rejection mechanism is developed using jerk analysis combined with the improved Interquartile Range (IQR) outlier detection algorithm, reducing high-frequency noise interference in the accelerometer. The Finite State Machine (FSM)-based adaptive Kalman filter identifies the motion state and dynamically adjusts drift compensation, enhancing the algorithm's stability. An Extended Kalman Filtering (EKF) fusion model is developed to construct an observation equation using the barometer's absolute height measurement and the accelerometer's relative displacement. The height estimation error is kept within 0.14mby leveraging the complementary characteristics of both sensors, providing a high-precision height reference for scissor lift in indoor operations. This method has broad application potential in indoor positioning and navigation.
Reinforcement Learning-Based Fault-Tolerant Control of Uncertain Strict-Feedback Nonlinear Systems With Intermittent Actuator Faults Qinmin Yang, Huaying Li, Zhengwei Ruan, Bo Fan, Shuzhi Sam Ge IEEE Transactions on Neural Networks and Learning Systems, 2025 In this work, a novel reinforcement learning-based adaptive fault-tolerant control (FTC) scheme with actuator redundancy is presented for a nonlinear strict-feedback system with nonlinear dynamics and uncertainties. A learning-based switching function technique is established to steer different groups of actuators automatically and successively to mitigate the impact of faulty actuators by observing a switching performance index. The optimal tracking control problem (OTCP) of strict-feedback nonlinear systems is transformed into an equivalent optimal regulation problem of each affine subsystem via adaptive feedforward controllers. Subsequently, the designed objective functions associated with Hamilton-Jacobi-Bellman (HJB) estimate errors caused by neural network (NN) approximations can be minimized by the reinforcement learning algorithm without value or policy iterations. It is proved that the tracking objective can be achieved and all signals in the closed-loop system can be guaranteed to be bounded, as long as the minimum time interval between two successive failures is bounded. Theoretical results are verified by simulations.
