This paper presents a magnetic integration scheme of LCL filter with symmetrical structure. This magnetic integration scheme uses EIE core to realize the inductor integration of symmetrical LCL filter, and realizes the decoupling and integration of upper and lower E-cores. The effectiveness of the magnetic integrated symmetrical LCL filter is verified by simulation and experiment. A 600 W single-phase SiC high-frequency inverter was used as the experimental platform to give the output current harmonic analysis results and conducted EMI noise. The symmetrical LCL filter with integrated structure not only has good harmonic suppression effect, but also greatly improves EMI suppression ability. The integrated filter is significantly smaller weight, helping to increase system power density. © 2023 IEEE.

Electrical explosion spraying, due to its high reaction temperature and intense mechanical effect, like strong shock wave and high-speed expanded explosive products, is a kind of satisfactory thermal spraying method. It had used to prepare single- or multi-element wire coating;however, the investigation of middle physical process was lacked, which was not beneficial to deeply understand the coating formation characteristics with the explosive process. In this study, a directional electrical explosion device was designed, which was available for synthesizing dense and homogeneous coating. Experiments were performed with intertwined Cu-Ni wire, and intertwined Cu-Ni-Al wire. Electrical and radiational diagnoses including current/voltage waveforms and self-emission images were used to investigate the explosive characteristics. SEM and XRD characterizations were used to study the morphology and crystallography of the produced coating. For intertwined two-wire (Cu-Ni) explosion, the parameters were measured separately to explore more details according to the corresponding dynamic high-speed images. The results indicated that the multi-wire explosion was non-synchronously with different explosive behaviors of wires;therefore, the discharge product channel showed a mixture of plasma, un-ionized metal vapor, and un-vaporized metal drops. Accordingly, the sprayed coating was composed by μm-scaled chunks or plates with some nanoparticles adhering on them. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

Nasal swab was intensively performed by medical workers during the COVID-19 pandemic, which unfortunately increases their infection risks. To solve this problem, this study aims to developing a robot to perform nasal swab automatically. An admittance control strategy based on the tangent-normal-binormal (TNB) frame is proposed to on-line adjust the path of the robot according to the external force/moment feedback, and confine the contact force within a pre-specified bound. Therefore, safety and comfort of nasal swab are enhanced. Experiments are conducted on a curved passage and a dummy. Quantitative performance indices are defined to evaluate the effects of the control parameters. The results show that the robot can automatically adjust its path to pass the swab through the curved passage while restrict the contact force within the pre-specified bound, despite inappropriate initial poses. Besides, experiments on the dummy show promising results for practical applications of the proposed nasal swab robot. © 2023 IEEE.

The advancement of cooperative autonomous vehicles has seen significant progress, often necessitating the use of high-cost tools. This paper investigates the utilization of a low-cost Rapid control Prototyping (RCP) platform, LoRra, for the development of autonomous vehicle functionalities. A modular prototyping vehicle equipped with Mecanum wheels was designed to operate within a cyber-physical laboratory test field, enabling the exploration of intelligent driving functions. The LoRra platform facilitates seamless model-based development, encompassing modeling, function design, automatic code generation, and real-time implementation. The effectiveness of the LoRra platform in developing and validating autonomous driving functions is demonstrated through extensive simulations and real-time experiments. This study highlights the successful application of LoRra in the speed control of traction motors and trajectory-following control, underscoring its potential as a cost-effective and versatile tool for research and development in intelligent mobility. © 2024 IEEE.

Autoencoder-based Metamodeling for Structural Design Optimization

引用

IFAC-PapersOnLine 2024年第28期58卷 288-293页

Metamodel-assisted optimization is a frequently applied approach for structural design optimization problems. Here, a data-driven metamodel approximates the computationally expensive simulation results of first principle models, e.g., finite element analyses. A significant drawback of typical metamodels is the limited amount of information that can be predicted due to their generally low-dimensional model output. Consequently, the metamodel usually does not predict the distribution of the desired quantity. This work presents a metamodel approach capable of predicting the spatial and temporal distribution of quantities for structural processes. This increases the modeling capability and makes more information available for the optimization. The autoencoder compresses the spatial distribution into a couple of features. The proposed methodology is applied to a three-stage forming process.
