Multi-sensing node convolution fusion identity recognition algorithm for radio digital twin by Guofeng WEI, Guoru DING, Yutao JIAO, Yitao XU, Daoxing GUO, Peng TANG

“…Electromagnetic space is an important link to empower and coordinate sea, land, air, space and network.Electromagnetic target recognition provides important radio target identity information for the twin construction of electromagnetic space, so that it can describe and depict the identity situation of electromagnetic targets in digital space.However, a single sensing node is vulnerable to interference, and its recognition performance is limited.Wrong recognition results will provide radio digital twin with conflicting identity information.Therefore, based on the requirements of radio digital twin in electromagnetic space, a radio target recognition framework for radio digital twin was constructed and a multi-sensing node convolution neural network individual identity fusion recognition algorithm was proposed.Compared with the nearest single sensing node, the recognition performance is improved by 6.29% by deploying the multi-node recognition network in the actual scene, which provides more accurate individual identity information.…”

Improved active disturbance rejection control for grid type photovoltaic energy storage system based on fixed-time convergence sliding mode by Zhenyang HU, Jiali WANG, Zuochao FU, Yueming LIU, Jinfeng HUANG

“…Among them，the fraction order extended state observer is designed to enhance the observation ability of the internal state of the system，and the fixed-time convergence sliding mode controller is designed to effectively suppress the chattering phenomenon in the traditional sliding mode control by means of its characteristic of converging to the equilibrium point in a fixed time，thus significantly enhancing the robustness and anti-interference ability of the system. Finally，through the construction of simulation model in MATLAB environment and experimental verification，the simulation and experimental results show that the control strategy proposed in this paper effectively reduces the transient voltage fluctuations of the system and speeds up the system response speed，which plays a positive role in improving the system performance.…”
