X-ray security check is a prevalent placement measure that plays a vital role in ensuring public safety. However, detecting prohibited items poses a complex challenge due to their variable sizes within X-ray images. In this study, we tackle this issue by curating a novel dataset through the integration of open-source data and introducing a Multiscale Feature Fusion Module. This module facilitates robust detection by amalgamating features across different scales. Extensive experiments verified that the superiority of our method compared to existing methods on the prohibited items test set constructed in this paper demonstrates extremely well the practical effectiveness of our proposed method. © 2024 IEEE.

In this paper,we focus on the tracking performance(TP) limitations of networked control systems(NCS s).The control system considered is a multi-input and multi-output(MIMO) discrete-time network control system with time delay,channel noise,packet dropouts,and logarithmic quantization communication *** modeling the channel,we assumed the channel noise to be additive white Gaussian noise(AWGN) and used a binary random process to model packet dropouts and a logarithmic quantizer to model the quantization *** explicit expression of the TP limitations of NCSs utilizing the two-degree-of-freedom(TDOF) controller is then derived using the frequency-domain approach,coprime decomposition,and Youla parameterization *** results show that the essential characteristics of the plant(locations and directions of nonminimum phase zeros and unstable poles) and network constraints(time delay,packet dropouts,quantization,and noise power spectral density) are closely related to the TP limitations.

In this article, the problem of decentralized adaptive proportional-integral (PI) tracking control is investigated for interconnected nonlinear systems subjected to unknown inter-connection delay. An input-driven filter is firstly designed for interconnected nonlinear systems under consideration to identify unmeasurable state variables. The difficulties arising from interconnection delay are conquered by the appropriate Lyapunov-Krasovskii functions. After that, a PI controller with decentralized adaptive tracking is designed, making use of backstepping control technique, which ensures closed-loop systems signals uniformly ultimately bounded (UUB) and tracking error converging to a bounded compact set. In design procedures, unknown nonlinear functions are approximated by BLS (broad learning system). In the end, the results of simulation are regarded as verification of the presented method. © 2023 IEEE.

Since in the process of crude oil exploitation, water inevitably is discharged into the crude oil storage tank, and moisture in crude oil can impair storage, transportation, and production. Therefore, crude oil should be dehydrated before entering the refinery and other further processing, and the drainage of the crude oil storage tank is a key link in the crude oil treatment. In this paper, a dehydration scheme and control logic of a crude oil storage tank is designed, and OLE for Process control (OPC)technology is used to realize the communication between the Programmable Logic controller (PLC) and the host computer. Based on Windows control Center (WINCC), a host computer monitoring system is Established to monitor the liquid medium in the buffer tank and in the tubes before and after the buffer tank in real-time. The dehydration process of the crude oil storage tank is completed by logical operation. This system has the advantages of high precision, convenient control, practicality, and safe and reliable work. © 2023 Technical Committee on control Theory, Chinese Association of automation.

Three-port photovoltaic energy storage system is a key technology in the field of photovoltaic power generation, which combines photovoltaic power generation and energy storage. Based on the research and application of bidirectional DC/DC converters, a three-port system is designed as a module.

This paper presents a novel 5-DoF (degrees of freedom) tilt-rotor quadcopter. Compared to traditional quadcopters, the vehicle offers more DoF by adding two servo-driven mechanisms. The extra DoF allow it to move at a constant pitch angle, thus adapting it to more scenarios, such as slope landings. In addition, the proposed tilt-rotor quadcopter can generate greater torque around the z-axis of the body coordinate system. This gives it an advantage in some scenarios, such as carrying a manipulator to turn valves in the air. In this paper, we first design and model the proposed tilt-rotor quadcopter. Then, we design the controller and control allocation algorithm for the proposed tilt-rotor quadcopter. The control allocation algorithm has clear analytical solutions, which benefits its implementation and deployment. Finally, the structure and control strategy of the tilt-rotor quadcopter are validated by an experiment. © 2024 IEEE.
