Abstract

This paper presents an efficiency optimization method for laser wireless power transmission (LWPT) system, focusing on the coordination and control of multiple laser diodes. A distributed laser wireless power transmission (D-LWPT) system is proposed, which includes multiple independent and parallel power transmission chains. The system has the characteristics of power scalability, redundancy, and control flexibility. The efficiency characteristics of each key component in the LWPT system are discussed. Due to the internal losses of the laser, the transmission efficiency is also affected by the transmission power. For distributed architecture, its flexibility allows for the rational allocation of transmission power. To achieve optimal efficiency, a central scheduling controller is designed to regulate the current of LDs. A swarm intelligence-based optimization algorithm is used to determine the optimal operating current. This significantly improves the system's efficiency and ensures real-time control. Experimental results validate the effectiveness of the proposed techniques. The DC to DC efficiency of the power transmission chain can reach over 14%, and the photovoltaic array can output a maximum power of over 130 W. The impact of beam combination on the efficiency and output power of PV arrays is less than 3%, indicating that the distributed structure does not affect system performance. The experimental results show that the proposed efficiency optimization method has excellent power following performance (algorithm execution time < 10 ms) and effective efficiency optimization performance. Under light load conditions, the LDs' efficiency is optimized from 27.5% to 45.0%, and under medium load conditions, it is optimized from 41.5% to 44.5%. This distributed structure and efficiency optimization method provide a solution for improving the performance of LWPT systems. [ABSTRACT FROM AUTHOR]

Abstract

This paper introduces a high-precision alignment method for laser wireless power transmission (LWPT) systems, integrating neural network-based target detection with a perturbation-observation technique. The objective is to enhance the alignment accuracy between the laser spot and the photovoltaic array, thereby improving energy transfer efficiency. The method's key feature is its ability to achieve these results without requiring additional optical components, simplifying system design. Continual assessment and adjustment based on real-time output power data ensure optimal alignment, maximizing the photovoltaic array power output. Experimental results demonstrated that the proposed method achieved an initial alignment precision with pixel errors below 3%, translating to a physical error of approximately 7 mm. Fine-tuning through the perturbation-observation method further optimized the alignment, resulting in a photovoltaic array power output of 98.70% of its maximum potential. This hybrid approach provides a reliable solution for boosting the performance of LWPT systems, offering significant potential for practical applications. [ABSTRACT FROM AUTHOR]

Abstract

Inverter-fed machines are widely used in electric vehicle drive systems and have shown a trend toward high voltage and frequency in recent years. They are subjected to multiple types of stress during operation, causing potential short-circuit fault damage to the stator winding insulation. Online condition monitoring of the insulation before or in the early stage of the short circuit fault can effectively reduce maintenance costs and ensure its health. This paper reviews and summarizes the deterioration mechanism and the recent online electrical monitoring techniques. First, four types of failure stress and each type's failure factors and mechanisms are analyzed. The coupling effect and overall process of multi-physical fields on stator insulation failure are considered. Secondly, the latest online electrical monitoring technologies are summarized. Each technique's principles, methods, advantages, and disadvantages are analyzed. Finally, existing problems and possible directions for improvement in current research are discussed, focusing on their feasibility and accuracy in practical applications. [ABSTRACT FROM AUTHOR]

11. AC Loss Investigation for Stacked HTS Cables With Gap Optimization

Author

Fu, Lin, Chen, Yu, Wang, Wenbin, Xu, Junqi, Sun, Yougang, Lin, Guobin, Kang, Jinsong, Chen, Xiaohong, Jiang, Shan, Chen, Wei, Yuan, Yupeng, Sheng, Jie, Wang, Yawei, and Shen, Boyang

Abstract

Cables made by HTS tapes usually have anisotropic dependence by magnetic field owing to the inherit anisotropic characteristics in HTS materials. By increasing number of tapes, the perpendicular magnetic field components weaken the critical current of the whole conductor, and also lead to larger AC loss during AC operation. To reduce the AC loss from stacked HTS conductors, this article studies gap optimization schemes between non-twisted stacked HTS tapes. Finite element modeling with performance comparisons for a stacked HTS conductor (10 tapes) using non-uniform schemes is demonstrated. The results indicate that gap optimizations have better impacts in AC loss reduction rather than those direct stacked conductors. Designs using non-twisted configurations would be simpler, cheaper, and more robust. Therefore, the gap optimization method can be used to explore high current design for large-scale HTS applications.

Abstract

Large-scale high temperature superconducting (HTS) magnets usually have tens of double/single pancake coil units. The structural optimization and manufacture of the magnet assembly result in varying axial gaps between adjacent pancakes. This brings additional difficulties for inserting the superconducting joints and dealing with the welding factors such as the gap, welding angle and overlapped length. This article presents the simulation modeling and general joint design guideline of a spiral joint scheme for large-scale HTS magnets and other similar applications. An easy-to-implement model has been built to characterize the physical behaviors of joint resistance. This article explores feasible joint design guidance and performance evaluation solutions for large-scale applications of HTS magnets having a series of HTS-HTS joints among pancake coils.

Abstract

This study presents a Two-Layer Deep Deterministic Policy Gradient (TL-DDPG) energy management strategy for Hydrogen fuel cell hybrid train, that aims to solve the problem that traditional reinforcement learning strategies require high initial values and are difficult to optimize global variables. Augmenting the optimization capabilities of the inner layer, a frequency decoupling algorithm integrates into the outer layer, furnishing a fitting initial value for strategy optimization. This addition aims to bolster the stability of fuel cell output, thereby enhancing the overall efficiency of the hybrid power system. In comparison with the traditional reinforcement learning algorithm, the proposed approach demonstrates notable improvements: a reduction in hydrogen consumption per 100 km by 16.3 kg, a 9.7% increase in the output power stability of the fuel cell, and a 1.8% enhancement in its efficiency.

29. Ultralocal Model-Free Adaptive Supertwisting Nonsingular Terminal Sliding Mode Control for Magnetic Levitation System

Author

Kang, Jinsong, Huang, Xiayi, Xia, Chang, Huang, Dongxiao, and Wang, Fengxiang

Abstract

The magnetic levitation technology has attracted blooming attention from all walks of life thanks to its superiorities such as noncontact and active control. While the intrinsic features of open-loop instability and strong nonlinearity, along with the uncertain external disturbance make the levitation control particularly significant and difficult. For speeding up the convergence and obtaining a better stability and disturbance robustness, this article proposes an ultralocal model-free adaptive supertwisting nonsingular terminal sliding mode control strategy for the magnetic levitation system. Different from the conventional model-based control, ultralocal model-free control breaks the constraint of a precise system model. Therefore, an improved second-order ultralocal model is established for the magnetic levitation system. For the benefit of finite time convergence and nonsingularity, the nonsingular terminal sliding mode surface is chosen. As a second-order algorithm, supertwisting (ST) algorithm can fundamentally suppress the chattering effect of the sliding mode control. An adaptive ST algorithm is designed for the further improvement of the system dynamic response. The stability of the proposed scheme is strictly verified based on the Lyapunov stability theory. Simulation and experimental comparisons with the existing control methods validate the exceeding performance of the proposed strategy under various operating conditions.

46. A Closed-Loop Evaluation Method for Industrial Robot Performance Driven by Health Data

Author

Kang, Jinsong, Fang, Hao, and Hao, Yufu

Abstract

Evaluating robot performance through health data is important for industrial robots in production. In this article, a closed-loop evaluation method based on low-cost health data is proposed to realize the evaluation of robot performance and contribute to robot optimization. Specifically, we first define a closed-loop evaluation structure between a robot system and its performance. Based on this, a multicluster cross-fusion algorithm based on K-means clustering is proposed to extract patterns of the performance based on the direction and magnitude of control errors instead of metrics to describe the robot performance. Then, objective and interpretable criterion sets are designed based on the strategies for robot system maintenance. The evaluation model based on hybrid game theory is proposed to realize the evaluation of the robot overall performance with the pattern of performance and criterion sets. Meanwhile, a closed-loop evaluation method based on an autoregressive nonlinear neural network and Bayesian model is used to evaluate the robot joint performance by mapping the performance to the robot joint. The effectiveness of the method is verified using an actual DoF robot. The results show that the method is sufficient for the evaluation of robot performance and optimization guidance.
