As the demand for reliable power supply in power systems grows, ensuring the performance of circuit breaker operating mechanisms is crucial. This performance is pivotal to the stability of the power grid, the speed of fault recovery, and the equipment's lifespan. In this paper, we introduce a structural optimization plan for a new magnetic control operating mechanism designed for 10kV circuit breakers. Employing three-dimensional and mathematical modeling, complemented by finite element analysis with Maxwell software, we delved into an in-depth study of the mechanism's structure, performance, and materials. We further conducted a parametric design and comparative analysis of key components. The simulation results, which exclude the spring load, demonstrate that the optimized circuit breaker can achieve a closing velocity of 3.07 m/s, an electromagnetic force peaking at 2.7 kN, and a closure time minimized to 8.5 ms. These enhancements notably improve the mechanism's closing efficiency. Consequently, our research introduces a novel perspective to the field of reliability studies for magnetic control operating mechanisms. © 2024 IEEE.

This paper presents the multilayer frequency selective surfaces for single-band and dual-band bandpass response. The unit cell of the proposed FSS comprises two identical metal patch elements in a back-to-back configuration with the complementary metal wire in between. Two dielectric substrates separate the three metal layers. The proposed single-band FSS exhibits a wide passband $(\mathrm{S}22 > -3\text{dB})$ bandwidth of 4.87 GHz. The proposed dual-band FSS exhibits a transmission pole at 5.52 GHz and a higher passband $(\mathrm{S}22 > -3\text{dB})$ with high selectivity from 10.66GHz to 11. $95\text{GHz}$ , Equivalent circuit models are established to explain their operation principles.

In the context of nonlinear and uncertain manipulator systems, achieving fast and accurate desired trajectories for each joint of the manipulator is crucial. Our study aims to improve current control methods by combining sliding mode control and neural network techniques. Specifically, we leverage the neural networks’ approximation capabilities to estimate both the modeling error and external disturbance in our research. These estimates are then integrated into the synovial control as additional gains. This approach allows for the sliding mode controller’s switch gain to adapt to changing modeling error and external disturbance, thereby avoiding the vibration production typically associated with traditional sliding mode controllers. It can be observed from the simulation results that the combination of the proposed nonsingular terminal sliding mode controller and neural network achieves fast and precise tracking of desired trajectories. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2024.

With the rapid development of astronomical observation, segmented telescopes with large equivalent aperture have attracted much attentions. However, it is an urgent problem to realize high-precision optical co-phase among sub-mirrors of the segmented telescope. High-accuracy and large-sized computer-generated holograms (CGHs) are expected to guide the co-phase alignment of sub-mirrors. Meanwhile, the large-sized CGHs are required with the enlarged aperture of telescopes. At present, it is hard to fabricate large-sized CGHs by traditional processing methods. In this paper, a stitching method is proposed to fabricate large-sized CGHs. © 2021 IEEE.

Large-area flexible roll-out solar array system has huge application potential in space structure especially for the Space Solar Power system (SSPS) due to the advantages of the lightweight, high area to mass ratio, excellent folding and deployable capabilities. For SSPS to operate economically, solar array system must operate at power levels greater than MW, while the commercial SSPS should operate at power levels no less than GW. Therefore, advanced flexible solar array systems with areas up to 104 m2 and 107 m2 are essential. In this study, a modular large-area flexible roll-out solar array system with several subarrays is proposed, in which Composite lenticular boom is used as the load-carrying structure, and inflation constrained with Velcros is designed as the drive mechanism. The single array can be expanded to more than 1000 m2, while the specific power is expected to reach more than 500 W/kg. In this paper, structural dynamics, inflation deployment dynamics and on-orbit thermal performances of the subarray are analyzed, the result show that the proposed solar array system is reasonable and feasible for SSPS application. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
