- Renewable resources are adopted nowadays to promote sustainable development, enhance energy security, and build resilient communities. The increase in demand for renewable resources has led to the use of photovoltaic systems. These systems must be efficiently monitored for fault and maintained properly for maximum productivity. Faults like cracks, dust, bird droppings and shadows may arise in the solar panel over a period, reducing the overall performance of photovoltaic systems. These faults can significantly reduce the lifespan of the solar panel. In this paper, voltage, current and surface temperature are measured using sensors from the photovoltaic panel. Real-time data from the solar cell via sensors are collected under no-fault, dust-induced, and partial shading-induced fault conditions. A fault detection methodology for photovoltaic (PV) systems is proposed using a combination of real-time power prediction and classification algorithms. Linear regression is employed to predict the fault. The fault is then classified using a random forest algorithm. ©2024 IEEE.

In multi-agent reinforcement learning, scalability is a significant challenge. Applying reinforcement learning algorithms in large-scale multi-agent systems requires consideration of algorithm efficiency. This paper attempts to reduce network parameter quantity and training time from the perspective of parameter sharing. However, parameter sharing may also bring some disadvantages, such as policy similarity, which may limit the formation of cooperative policies and affect the efficiency of the entire system. To address the problems caused by parameter sharing, this paper proposes a multi-agent reinforcement learning algorithm with role parameter sharing (R-PS). By dynamically dividing roles and selecting objects for parameter sharing, R-PS automatically identifies intelligent agents that may generate beneficial parameter sharing and conducts partial parameter sharing within the roles. Meanwhile, intrinsic rewards are introduced to increase the diversity of agent strategies. Experimental results show that R-PS can effectively divide roles, benefit from partial parameter sharing, and form diverse policies through intrinsic rewards. It also reduces training time, produces excellent performance and collaboration. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.

The combination of Electric Autonomous Vehicles (EAVs) and renewable energy aligns with sustainability goals. However, to achieve these goals, it’s necessary to implement a robust control system for the key component that drives the vehicle, specifically, the electric motor. This paper explores the control of Induction Motor pursuing the Required Performance Standards for Autonomous Vehicles. The primary objective is to build a robust control system to achieve this, the first approach is the Indirect Rotor Field Oriented control (IFOC), the Latter is implemented along with a PI controller, Lastly Model Reference Adaptive control by Hyperstability Criterion is introduced. A detailed analysis is carried out using MATLAB Simulink, which shows the efficiency of adaptive control not only in speed tracking, but also in parameter variation and disturbance. The comparative analysis between PI and Hyperstability control method validates the theory asserting the robustness and insensitivity of adaptive control to parameter uncertainty and disturbances. Furthermore, it convincingly demonstrates that the latter outperforms traditional classic controllers. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2024.

Sneak circuit analysis is a crucial reliability design process. In the design of spacecraft electronic systems, it is challenging to identify sneak circuits related to integrated chip interface circuits, and there are few targeted researches. In extreme working conditions, the coupling sneak circuits caused by the failure of integrated chips are difficult to identify, affecting the design optimization. The paper proposes a typical interface information specification model for integrated chips to simulate the electrical information characteristics of interfaces. And the typical failure models of intrinsic components inside the chip are determined through multi-physics field analysis. Then, based on the digital model, a sneak circuit diagnosis process based on excitation and fault injection are proposed, and a sneak circuit screening method based on Python virtual prototyping is implemented in the case study. Finally, the design constraint clues for the chip's external circuit are obtained, which provides a reference for related fault diagnosis and reliability optimization works. © 2024 IEEE.

The accurate prediction of behaviors of surrounding traffic participants is critical for autonomous vehicles (AV). How to fully encode both explicit (e.g., map structure and road geometry) and implicit scene context information (e.g., traffic rules) within complex scenarios is still challenging. In this work, we propose an implicit scene context-aware trajectory prediction framework (the PRISC-Net, Prediction with Implicit Scene Context) for accurate and interactive behavior forecasting. The novelty of the proposed approach includes: 1) development of a behavior prediction framework that takes advantage of both model- and learning-based approaches to fully encode scene context information while modeling complex interactions;2) development of a candidate path target predictor that utilizes explicit and implicit scene context information for candidate path target prediction, along with a motion planning-based generator that generates kinematic feasible candidate trajectories;3) integration of the proposed target predictor and trajectory generator with a learning-based evaluator to capture complex agent-agent and agent-scene interactions and output accurate predictions. Experiment results based on vehicle behavior datasets and real-world road tests show that the proposed approaches outperform state-of-the-art methods in terms of prediction accuracy and scene context compliance.

Utilization of waste heat is one of the most important parts of energy efficiency. There are several possibilities for this calculation, in this thesis we partly relied on the theory of similarity. The target of using waste heat is to achieve the best possible system efficiency within a complex system. Measurement of the drive motor, torque converter, inverter, battery and shaft connection must be examined together. We summarize the results of this work. © 2023 IEEE.

Modern active distribution networks possess significant potential to deliver ancillary services to transmission networks owing to the rising integration of renewable energy sources. This study explores the provision of primary frequency support from active distribution network to transmission network via price-based transactive control of microgrid inverters. The proposed method aims to achieve efficient coordination among microgrids, optimizing their utility, while also assisting the active distribution network in optimal primary frequency support provision to transmission network.

Recently, legged robots have attracted considerable attention as highly mobile rovers for planetary exploration. However, the surfaces of celestial bodies such as Mars and the Moon are primarily loose, causing slippage due to surface deformation from the rover's leg movements. To mitigate this, a walking method aimed at preventing slippage was proposed. In this walking method, the bearing capacity is increased by imparting vibration from the rover's leg to the loose soil on the ground. This walking method improved the mobility performance of the legged rover. It is crucial to investigate the increase in bearing capacity by imparting vibration in a realistic space environment to validate the effectiveness of the proposed method. This study examines the change in bearing capacity due to vibration under low atmospheric pressure, a condition found on Mars and the Moon. This condition affects the characteristics of ground sand due to decreased air resistance. Our findings provide valuable insights into using vibration in planetary exploration to enhance the performance of legged rovers. The experimental results indicate that the bearing capacity under low atmospheric pressure is nearly identical to that under standard atmospheric pressure, suggesting that atmospheric pressure conditions have minimal impact on the bearing capacity when vibration is applied. © 2024 International Society for Terrain-Vehicle systems.
