Dynamic wireless power transfer (DWPT) system has the problem of unstable transmission power caused by the change of coupling coefficient in the process of power transmission. This paper proposes a finite control set model predictive control (FCS-MPC) strategy based on mutual parameter identification for dynamic wireless power transfer system. The transmission characteristics of DWPT system with LCC-S resonant compensation topology is analyzed, and the output current of the inverter in the primary side is taken as reference for mutual inductance identification by particle swarm optimization (PSO) algorithm. Then, the FCS-MPC algorithm based on PSO is used to control the output voltage by changing phase-shift angle in the primary side. For precise control, the compensation calculation of the phase-shift angle is added. The simulation at the end of the paper verifies the accuracy of the PSO algorithm and the effects of proposed strategy under different coupling coefficients and load. The results indicate that the proposed strategy has fast transient response and stable power transmission in DWPT system which can be used to improve the system performance. © 2023 IEEE.

The tilt of the leveling ship in the leveling process has to meet the high precision process requirements while at the same time minimizing the actuator action frequency in the control process and extending the actuator life, which is very important for leveling processes with time delays and complex external disturbances. A group of advanced control strategies must be designed to match them. Firstly, a ballast leveling mechanism model is established based on the hydrostatic characteristics of the ship, followed by the design of a multi-switch device predictive control algorithm. By making the rolling time domain larger than the maximum time delay and ensuring that the switchgear combination is constant in the time domain, LESO is introduced for online prediction of unpredictable disturbances and rolling optimized predictive control of the equipment combination, the influence of time delay and external disturbances on the control system is weakened, and the switching frequency of switchgear is reduced. In the final simulation, the tilt tracking RMSE was reduced by 22.2% compared to conventional switching control, and the number of actuator switches was reduced by 6%. © 2023 SPIE.

Dynamic operation of anaerobic digestion plants requires advanced process monitoring and control. Different simplifications of the Anaerobic Digestion Model No. 1 (ADM1) have been proposed recently, which appear promising for model-based process automation and state estimation. As a fundamental requirement, observability and identifiability of these models are analyzed in this work, which was pursued through algebraic and geometric analysis. Manual algebraic assessment was successful for small models such as the ADM1-R4 and simplified versions of the ADM1-R3, which were derived in this context. However, for larger model classes the algebraic approach showed to be insufficient. By contrast, the geometric approach, implemented in the STRIKE GOLDD toolbox, allowed to show observability for more complex models (including ADM1-R4 and ADM1-R3), employing two independent algorithms. The present study lays the groundwork for state observer design, parameter estimation and advanced control resting upon ADM1-based models.

Ensuring precise train localization is crucial for the operational safety and efficiency of railway networks. Conventional localization techniques face limitations due to dynamic environmental noise, impacting the accuracy of such systems. In response, this study proposes a sophisticated approach that incorporates a deep learning-enhanced Invariant Extended Kalman Filter, utilizing a Convolutional Neural Network-Long Short-Term Memory (CNN-LSTM) architecture. This innovative method dynamically adjusts the noise parameters within the Kalman filtering process. The CNN component extracts spatial features, while the LSTM module analyzes temporal sequences, thereby optimizing the filter's performance under varying environmental conditions. The integration of Global Navigation Satellite System (GNSS) and Inertial Navigation System (INS) data forms the core of our investigation, addressing the complexities inherent in train localization tasks. Rigorous evaluations on real-world datasets have demonstrated a notable enhancement in localization accuracy, achieving a [specific improvement percentage] over conventional Kalman filter methods. The outcomes of this research underscore the transformative impact of deep learning on railway system advancements and set a foundation for subsequent innovations in intelligent transportation systems. By merging advanced deep learning algorithms with traditional signal processing, our work contributes to the evolution of more dependable and efficient train localization solutions, paving the way for future developments in this critical area of intelligent transportation systems. © 2024 Technical Committee on control Theory, Chinese Association of automation.

To safeguard the operation of ultra-high voltage transmission lines, this study introduces a technique for dynamically monitoring potential security threats to these lines. This technique integrates images and point cloud data to pinpoint and measure the distance of objects intruding into the vicinity of the transmission lines. The methodology focuses on achieving high-precision localization and distance measurement of such objects. Key innovations include advanced image object detection combined with efficient processing of point cloud data. This allows for precise location and reliable distance assessment of objects at significant distances. The process begins with the creation of detailed scene point clouds using unmanned aerial vehicle (UAV) SLAM mapping technology. These point clouds are then aligned with the monitoring LIDAR coordinate system through registration algorithms to use the catenary line model to reconstruct transmission lines. The intrusion's highest point is precisely located by correlating two-dimensional image detection results with the image-to-point cloud mapping and extracting the intruding object's point cloud using Euclidean clustering. The method concludes by calculating the minimum distance from the top of the intrusion to the nearest transmission line, using the catenary line equation. Experimental results indicate that this approach can detect intruders and gauge their distances efficiently and accurately across various ranges and environmental conditions, showcasing exceptional accuracy and robustness, particularly in long-range object detection scenarios. © 2024 Technical Committee on control Theory, Chinese Association of automation.
