A S-type engagement of beyond-visual-range (BVR) air combat tactical method based on sliding mode control is proposed, which is aiming at the problem of Doppler pulse (PD) radar blind zone. By introducing the Electronic Support Measures (ESM), the whole tactical process is divided into two sub-processes: quick engagement and stealthy engagement. This paper designs a stealthy engagement processcontroller based on the double power sliding mode control, and a quick engagement processcontroller based on the back-stepping second order sliding mode. The simulation experiment shows that our aircraft can use EMS to judge the enemy radar detection information and switch the strategy. And it can successfully enter the enemy radar blind zone through S-type maneuver, occupy the dominant area, which can effectively complete the stealthy engagement.

The battery energy storage system (BESS) can quickly supplement the power demand of the power load and absorb the peak power generated by new energy. Therefore, the installed capacity of the BESS in the power system continues to increase, and it has been more and more widely used in the frequency modulation control of the power system. A fuzzy logic based control method for BESS to participate in power system frequency regulation control is proposed. The area control error (ACE) signal and the state of charge (SOC) of the energy storage battery are used as control inputs, thus the frequency regulation demand determined by ACE signal and the SOC limit of the energy storage battery are integrated to realize both health management of the energy storage battery and the frequency regulation control of the power grid.

The world faces one of the crucial issues - waste management, which needs to be tackled urgently to minimize environmental pollution. The main challenge is to classify the massive amount of waste reliably and accurately. Many existing deep learning models employed to achieve accurate results still require to be improved as their performance varies on a different dataset. This research proposes an algorithm based on fine-tuned convolutional neural networks (GoogleNet, ResNet, DenseNet, ResNeXt, EfficientNet) using two distinct optimization algorithms (SGD momentum, Adam) to classify an open-source dataset into twelve classes. Experimental results reveal that the fine-tuned ResNeXt neural network model achieves high model accuracy, 95 %, with a small number of epochs. The experiment indicates that our achievement outperforms several counterpart methods.

Shelling scallops can be a labor-intensive and repetitive task that can lead to musculoskeletal disorders for the operators. The repetitive nature of the task and the force required to open the scallop shells can significant strain the hands, wrists, and arms of the operators. In this study, we explored the automation of the shelling process in the seafood industry. We introduced a new mechatronic system called CoboShell, which automates the opening of scallops and the cutting of the nut muscle using a collaborative robot (cobot). CoboShell ensures the preservation of the quality of the fresh sea product. Initially, we addressed a technological challenge by proposing an integrated solution based on the Venturi effect. We used appropriately sized suction cups to handle the non-uniform surfaces of the shells. Subsequently, we focused on a scientific inquiry involving the control of the knife blade’s trajectory using a cobot. The goal was to guide a flexible knife blade along the inner flat part of the scallop shell. This process aimed to cut the nut muscle and separate the two parts of the scallop. For that, the entry point of the knife is determined automatically in the centre of the scallop opening using an Artificial Intelligence (AI) based technique. Finally, experimental results as well as the repetitive tests have shown that the cobot provided better quality on the muscle cutting with high accuracy and cadence, comparing to conventional industrial arm in the automation of the scallop shelling process.

In recent years, advanced information technology, network technology, Internet of Things technology, cloud computing technology and so on are developing rapidly, which has played an important role in promoting the development and reform of the society. The application of these advanced intelligent technology in mechanical and electrical engineering has greatly improved the quality of the project while reducing the construction cost. Mechanical and electrical installation and construction has an important impact on the economic benefits of enterprises. Mechanical and electrical installation engineering has many equipment types and involves many professional fields, so we should fully master the mechanical and electrical installation technology to ensure targeted construction, so as to comprehensively improve the project progress. Firstly, this paper briefly describes the prefabricated board installation process and optimization method. Secondly, the prefabricated mechanical and electrical installation process in intelligent engineering is optimized by using the characteristics of artificial intelligence. Finally, the practical application proves that the flexible use of prefabricated installation and construction technology in the installation and construction process of intelligent mechanical and electrical machinery is beneficial to saving resources and energy, improving labor production efficiency and quality and safety level.

The article considers possible approaches to designing program modules in web application clients. A design approach is proposed, the use of which provides an increase in the ease of debugging programs in the development process, localization of errors and reduction of program code duplication. The proposed design approach is based on the division of responsibility between parts of the program code for the implementation of synchronous and asynchronous operations in asynchronous events. Responsibility for processing network interaction with the server and receiving data from the user through controls in the user interface should be assigned to asynchronous operations and their responsibility should be limited only to receiving data from external sources. In turn, updating the application state based on data from external sources should be limited to the responsibility of synchronous operations. The paper shows how the proposed design approach provides the above improvements and provides examples of program code.

This paper presents the development of identification based fuzzy supervisory control for application to pressure process. The system identification is carried out using an integral based method that reformulates the differentials with an integral, that provides robustness to noise. A theoretical analysis of the identification method is also provided. Pressure data was obtained through the use of a pressure guage which is connected to a workstation via a DAQ. The collected data was then identified using the developed identification algorithm. Appropriate PID gains are firstly selected by pole placement methodology, where they are later modified with fuzzy rules according to the desired responses. Results show that the designed fuzzy supervisory control outperformed the constant PID gains which was designed by pole placements.

In this paper, the collision avoidance process of underwater vehicles is considered, and an improved potential function is proposed to reduce the energy consumption of underwater vehicles when approaching the target position. Aiming at the negative gradient of the potential function in the controller, the potential function based on target position is proposed to prevent underwater vehicles from oscillating near the target position due to the excessive negative gradient of the potential function. Then, the Lyapunov function is used to prove that the potential function can achieve the purpose of underwater vehicles collision avoidance [1], and the improved potential function is compared with the general potential function during collision avoidance. Finally, two potential functions are compared by simulation, which shows the advantage of improving the potential energy function in reducing unnecessary energy consumption.
