This paper proposes a novel spectral normalized neural networks funnel control approach for servo system with unknown dynamics. The approach introduces spectral normalization technology into the funnel controller design to address the unknown dynamics. Spectral normalization techniques can restrict the spectral norm of the weight matrices of the neural networks, leading to more stable and robust networks. The spectral normalized neural network exhibits strong generalization ability and can adapt to offline learning strategies, which significantly reduce the system's computation cost. Moreover, based on the funnel control architecture, the system output is constrained to remain within an acceptable boundary, optimizing transient performance and guaranteeing satisfactory controlperformance. All signals of the closed-loop system are bounded based on Lyapunov stability analysis. Finally, simulation results demonstrate that this approach provides commendable tracking performance and superior generalization capabilities.

This brief presents a dual-band (DB) high-efficiency power amplifier (PA) with extended bandwidth. A novel output matching network (OMN) that integrates harmonic control into DB fundamental matching design is proposed. Bandwidth of the DB PA can be efficiently extended by the OMN presented since it can offer DB broadband harmonic control while maintaining the input impedance at DB fundamentals. By precise control of the characteristic impedance on the part dual transmission line (part-DTL) and the double shunt stub (DSS), these two structures are made equivalent to the series and parallel transmission line (TL) performance at DB fundamentals. Additionally, the part-DTL modulates the input impedance in broadband near DB harmonics to pure reactive, and the DSS optimizes the imaginary part of the input impedance at DB harmonics. For validation, a DB PA is designed and fabricated with a Cree CGH40010F GaN transistor. The fabricated DB PA features the saturated output power of 42.4 dBm and 41.7 dBm with the power-added efficiency of 73.5% and 68.4% at 2.6 GHz and 3.5 GHz, respectively. Specially, the bandwidth of the DB PA is extended to over 300 MHz and 200 MHz.

Aiming at the problem of insufficient computing resources for SLAM calculations in multi-robot systems, a multi-robot collaboration system based on the 5G edge computing platform (MEC) framework is proposed, and a map merge algorithm based on computer vision is designed. First, the main problems of SLAM map construction under multi-robot systems are analyzed, and solutions are given;secondly, a multi-robot collaborative SLAM system based on 5G MEC is studied;finally, AKAZE feature detection is used to improve the map merge algorithm to enhance the global map. The algorithm's performance and the system's effectiveness are verified by simulation and physical experiments, respectively. The experimental results show that the real-time robot collaboration system based on the 5G MEC framework proposed in this article performs better in map merge. The algorithm has calculation speed and communication delay advantages and will promote research on 5G network applications in real-time robot collaboration.

The objective of this paper is to present a proposal for a new control hardware architecture that supports the practical implementation of integer- and fractional-order controllers. This control hardware architecture exhibits various significant features: From the hardware point of view, the proposed architecture offers the possibility of using different conventional control technologies, namely, computer control, real-time microcontroller-based control, and FPGA-based control. From the software point of view, LabVIEW is used as the unique programming language, regardless of the selected control technology. Some examples are presented in which fractional-order controllers are implemented using different control technologies in order to demonstrate the applicability and effectiveness of the proposed control hardware architecture for this purpose. Some hardware implementation issues are also discussed in this context. Finally, some final remarks and conclusions are provided.
