(Online) Speech Title: Fundamental Concepts and Principles of Agricultural Energy Internet
Abstract: In the context of achieving carbon neutrality, while considering the influence of meteorological conditions on both energy and agricultural systems, we conducted an in-depth exploration of the core principles underlying the Agricultural Energy Internet. We systematically structured the theoretical foundation of Agricultural Energy Internet by merging insights from facility agriculture science, electrical science, and information science. This framework primarily focuses on promoting the sustainable co-development of energy systems and agricultural production. Furthermore, we accounted for disturbances related to agricultural and energy meteorology and successfully coordinated agricultural materials, energy resources, and sensor data based on the fundamental characteristics of material flow, energy transfer, and information exchange during their respective processes. Specifically targeted at energy-intensive agricultural production settings, such as fully electrified farms and fisheries, we introduced secure analysis, operational optimization, and planning methods aimed at fulfilling agricultural energy demands.

(Onsite) Speech Title: Mathematical Model for High Precision Detection and Flow Evaluation of SF6 Gas Decomposition Products under Lightning Impulse
Abstract: With the proposal of a new type of power system in China, the mathematical Model the AC-ISODATA-PSO joint clustering algorithm is applied to predict the content of decomposition products of foam ceramics in field application problem. By iteratively optimizing optical fiber sensing system through structural iteration, the impact of the high-frequency vibration, the large temperature difference, and the extremely short detection period on the experimental results of the high- voltage equipment is addressed. The optical system adopts the single beam dual wavelength structure, which determines the type of air chamber in the refracted optical path and improves the system sensitivity. The high-performance single-chip microcomputer with the multi-channel 12 bit accuracy analog digital converter is used to further improve detection accuracy, providing optimized the optical path detection system for the subsequent foam ceramic demonstration applications.

(Onsite) Speech Title: Sensorless Position Servo System - From Motor Topology to Control Strategy
Abstract: As the representative of advanced manufacturing technology, robots and their servo systems have grown rapidly in recent years. In 2022, global robot sales reached 51.3 billion USD, with services and special machines accounting for 62.0%. It is expected that by 2024, this share will further increase to 65.2%.
As the motion mechanism for robots, position servo systems directly affect their adaptability in special environments. The variable and harsh working environment, such as high temperature, strong magnetism, radiation, vibration, etc., pose serious challenges to the reliability and compactness of servo drives.
The mechanical position detection of servo motor rotor is a key link in the control of special robots. However, existing optical and magnetic encoders are highly susceptible or even damaged by those adverse factors in special environments, causing servo system failure. Moreover, the axial space occupied by the encoder and its decoding circuit decrease the torque density of servo systems. Although sensorless control has been widely used in speed closed-loop control systems, there is hardly effective solution for sensorless control of position closed-loop systems due to the periodic symmetric distribution of motor magnetic field.
This report proposes a new motor structure and control strategy to address the aforementioned challenges, which not only improves the power density and reliability of the position servo system, but also achieves sensorless control of the rotor mechanical position.

(Onsite) Speech Title: Design and Realization of High-Capacity, Stabile and Safe Li–S Batteries

Abstract: Due to its low cost and ultra-high theoretical energy density of 2600 Wh/kg, Li-S battery becomes one of the promising next-generation energy storage devices. However, it is still challengeable to solve the severe shuttle effect of sulfur cathode and the potential safety of lithium metal anode. To address such issues, herein, we present a synergistic strategy by rational structure design of functional separator and composite sulfur cathode to realize high-capacity, stabile and safe Li–S batteries.
Firstly, we have designed a series novel functional interlayers and fabricate on commercial PP separator to suppress the shuttle effect of lithium polysulfides (LiPSs), and to inhibit the uncontrollable growth of lithium dendrites. For example, the Li–S cells with Co9S8 interlayer separator deliver high initial specific capacity of 1385 mAh/g with a retention of 1190 mAh/g after 200 cycles, and deliver a high capacity of 530 mAh/g at a 1C rate (1675 mA/g) even after an impressive number of 1000 cycles with an average capacity fade of only 0.039% per cycle. The Fe3N@NG functionalized separator displays excellent electrolyte wettability, high Li ionic conductivity and ion transference number, which function synergistically to suppress Li dendrite growth. Meanwhile, the DFT calculation demonstrates that there exists a stronger interaction between Li atoms and Fe3N@NG, which can provide the deposition sites, resulting in uniform and compact Li plating.
Then, we design and fabricate several kinds of sulfur composite cathode, including graphene or CNT based skeleton, and sulfiphilic and lithiophilic metallic compound, to increase the sulfur utilization, enhance the capacity and cycling stability. For example, when well designed YSC@Fe3O4 nanoboxes is employed as sulfur host, the Li-S cell with delivers a high initial capacity of 986 mAh/g at a 1C rate with a capacity retention as high as 83.2% even after a remarkable number of 1500 cycles. 1T'-MoTe2 quantum dots decorated three-dimensional graphene (MTQ@3DG) was prepared to overcome these issues, and it accomplished exceptional performance in Li-S batteries. Owing to the chemisorption and high catalytic effect of 1T'-MoTe2 quantum dots, MTQ@3DG/S exhibits highly reversible discharge capacity of 1310.1 mAh/g at 0.2 C with 0.026% capacity fade rate per cycle over 600 cycles.
Our study presents a synergistic strategy by rational structure design of functional separator and composite sulfur cathode to effectively realize high-capacity, stabile and safe Li–S batteries.
